Frankly I’m tired of the rollercoaster that the Coalition’s NBN has been. First came the dread the dread that when they came to power we’d end up with an inferior product, one that would be completely outdated by the time it was implemented. Then a small beacon of hope flickered with Turnbull stating fervently he’d wait for a technology review as well as a cost/benefit analysis before he’d move forward with any changes. Of course the review comes out and it’s deeply flawed, showing that the exercise was nothing but an excuse for the Coalition to go ahead with their inferior plan. All hopes that the Coalition would keep their promises from then on were dashed however many thought Turnbull would still hold off on any decisions until the magical cost/benefit analysis was completed (something which he continually lambasted Labor for).
Of course that turned out to be a fucking lie.
Worse still news comes today that the much vaulted minimum speed guarantee, the one where everyone would get access to at least 25Mbps “sooner, faster and cheaper” than the Labor NBN, is also fucking gone. This isn’t a case of them promising “up to” 25Mbps and all of us not remembering it properly, it’s right there on their website (I’ve also taken a screenshot for posterity):
While 25 mbps will be the peak speed on the satellite and fixed wireless services (under Labor’s plan for under the Coalition’s), it will be the floor speed under the Coalition’s plan and most consumers in the fixed line footprint will be able to access 50 mbps or faster.
So now we’re getting a NBN with a mix of technologies, some of which will require substantial remediation, that will still run predominately on the old copper network and the magical guarantee of 25Mbps (which we were all pretty sure was a lie anyway) has also disappeared in a puff of broken promises.
I wish I could say I’m not angry, just disappointed (as we’ve all felt the sting of that line from a parental figure at one stage in our lives) but honestly I’m just fucking angry. They ran a whole election campaign on honesty and integrity and right after they get in everything they promised has turned out to be a complete and utter farce. It’s so bad now that even those who could’ve been called supportive of the Coalition’s NBN are turning on them and many technical news outlets are simply giving up, unable to trust anything the government says. I was pretty much of the same mind until I read that the speed guarantee was going away which just added yet another insult to the numerous injuries that the NBN has endured.
Worst part about all this? We’re stuck with this hypocritical, untrustworthy government for at least another 2 years and it’s clear that no amount of political toxicity will change their minds on the NBN matter. So the best case scenario is that NBN takes so long to transition to the new scheme that by the time the next election comes around the Coalition gets turfed and no substantial work on the shitty Coalition NBN has been done. It’s a fairy tale ending, I know (there hasn’t been an one term government in at least 80 years, as far as I can see) but it’s the only hope we have of getting something that isn’t a complete trainwreck like what the Coalition is proposing.
I could go on but I know all the ranting in the world on this blog isn’t going to change anything. All I can hope for is that Australia has its fill of an Abbott government by the time the elections roll around and they give him the boot he so rightly deserves. Of course that won’t stop me writing about the various fuckery that Turnbull and co get up to with regards to the NBN, but I know I’m preaching to the choir here.
Australia is an incredibly strong country economically being ranked as the 12th largest by GDP of all countries in the world. When you then consider that our population is a fraction of that of many countries that are above us (Canada is the closest in size and is in 11th spot with a population about 50% bigger than ours) it means that, on average, Australians are more wealthy than their global counterparts. This is somewhat reflected in the price we pay for certain things however it doesn’t take a lot of effort to show that we pay more than you’d expect for many goods and services. The most notable being media as we lack any of the revolutionary services that drive their prices down (Netflix, Hulu, etc.) or any viable alternatives. It gets even worse though as it seems we also pay more just to go to the cinema.
The graphic above shows that Australia, along with a few other developed nations, pay an extraordinary amount more than others do when the costs are normalized. The differences between the lowest and the highest aren’t exactly huge, you’re looking at a spread of about $15 from the cheapest to the most expensive, however this is yet another indication of just how much more Australia pays for its media than anyone else does. In essence we’re paying something on the order of 25%~50% more for the same product yet the excuses that the industry once relied on, that Australia is “really far away”, don’t really hold water anymore.
It should come as little surprise then that Australians are then far more likely to pirate than any other developed country, sometimes representing up to almost 20% of new release piracy. There have been some inroads made into attempting to reduce this number, with a few stations “fast-tracking” episodes (although they still usually carry a delay) or giving users access to an online option, however the former doesn’t solve the problem entirely and the latter was unfortunately repealed. The hunger for the media is there it’s just that a reasonably priced option has failed to materialize for Australian users (and if you mention Quickflix I’ll gut you) which has led to these dramatic figures.
Now I’d be entirely happy with doing the slightly dodgy and getting myself a Netflix or Hulu account via a VPN or geo-unblocking service however my bandwidth isn’t up to the task of streaming media at 720p. Sure it could probably do a lower resolution but I didn’t invest as much as I did in my entire home theatre system to have it operate at a sub-par level. This issue was supposed to go away with the NBN being just around the corner but I literally have no idea when that might be coming nor what incarnation of it I will end up getting. So it seems that, at least for now, I’m stuck in digital limbo where I either fall to piracy or being gouged repeatedly.
Neither of these issues are beyond fixing and indeed it’s been shown that once a reasonably priced alternative becomes available people ditch piracy in a heartbeat. Heck I know that for me once Steam became widely available my game spend increased dramatically, especially after I found sites like DLcompare. I can assure you that the same will happen once a media based alternative comes to Australia and I’m not the only one who has the disposable income to support it.
I can think of a few titles where bugs or glitches were not only expected they were also thought of being one of the many sources of enjoyment of the game. The Elder Scrolls series is a prime example of this as their titles are almost always riddled with numerous bugs on release and Bethesda’s stance of not fixing the fun (but not game breaking) shows that many players get an awful lot of enjoyment out of their game behaing unexpectedly. I had yet to see a game where bugs, glitches and weird physics were actually the game itself until I came across Goat Simulator, a title from indie game developer Coffee Stain Studios. Whilst it’s definitely an unique concept there’s a limit to how much whacky physics fun you can have before you start to tire of it.
You’re a goat (surprise surprise) and the game centers around you being a goat in a section of a small town. Strictly speaking there are no objectives, there’s no over-arching plot to drive you forward nor any motivation provided for you being where you are, and so you’re free to roam the world doing as you wish. In traditional Goat spirit this of course means destroying anything and everything in your path, headbutting anything that might get in your way. Once you tire of that though there are many hidden challenges for you to unlock, some of which provide you access to powers beyond your wildest goaty dreams.
For a game that was slapped together in the space of a couple months Goat Simulator has a level of graphical fidelity that I honestly didn’t expect. It uses the Unreal 3 engine so you wouldn’t expect graphical miracles from it but the incorporation of atmospheric effects and modern lighting has Goat Simulator punching well above its weight class in terms of graphics. It still runs perfectly fine most of the time too (until you’re intentionally trying to break it, of course) something which, again, I wasn’t expecting. In all honesty for a game that was being touted as a bug ridden, hastily slapped together prototype there’s an incredible amount of polish. Much more than I’d come to expect from other developers of similar calibre.
Goat Simulator revolves around you being a goat that causes all sorts of carnage around the small suburban area that you find yourself in. In the beginning this will be pretty vanilla kind of stuff, destroying fences, headbutting people and generally running amok in the various areas available to you. This is all scored though so whilst your initial inclination will be to just ram things at random eventually you’ll try to figure out how to maximise your score. That’s when you’ll start to add a little strategy into your carnage, looking for places with a cornucopia of objects that you can goat your way through. Of course along the way you’ll run into the hastily slapped together physics that provides much of Goat Simulator’s entertainment.
I started out by just following the prompts to try out different things which serves as a solid, light touch tutorial that doesn’t get in the way if you just want to rampage through the town. This introduces you to how the scoring mechanics work which are pretty similar to what I remember Tony Hawk Pro Skating being like when I last played it almost a decade ago. So whilst you can headbutt that box 100 times in a row your score probably won’t go up by much as the game wants you to try a variety of different whacky things. This helps to add a little direction to a game that would otherwise have been thoroughly confusing without trying to impose on those who couldn’t care less about it.
After a while though there’s really only 2 things that will keep you playing: score and achievements. For the most part getting the highest score is just a matter of patience and not breaking the game too hard (as that can lead to you needing to restart it or the game crashing). something which can only take you so far. The achievements provide some fresh perspective on the game by giving you access to “powers” which can be anything from dropping dead goats from the sky to an impossible to control jetpack. If you’re like me though once you’ve done most of these the rest of the achievements don’t really seem that appealing and all you’re left with is a haphazard physics simulator.
Which, I have to say, is an awful lot less buggy than I thought it would be. You can make the physics engine do some crazy things but they’re really nothing above what I’ve seen in other games that were supposedly coded with good physics engines. You can get people stuck in the wall and launch yourself into the stratosphere but other than that there’s really not much else to speak of. Even when I was deliberately trying to make the game crash (by spawning dozens of other goats and using the console to fiddle with engine settings) all I could accomplish was making the physics engine and game slow to crawl. So if you were expecting a game that was absolutely riddled with bugs you might be disappointed as it’s really anything but.
Goat Simulator is a fun distraction that showcases the enjoyment that gamers can get from emergent game play. Whilst it’s far from the bug laden, glitch filled adventure that many touted it as the core game mechanics are still fun with the added benefit of a whacky physics engine just adding to the mix. It’s a short lived adventure however as whilst it’s fun to rack up a high score there’s nothing really to keep you interested once the achievements are gone and you’ve played with all the powers. If the idea piqued your interest then I definitely recommend grabbing it but otherwise you’re not really missing out on anything if you decide not to play it.
Goat Simulator is available on PC right now for $9.99. Total play time was 2 hours with 62% of the achievements unlocked.
At a high level I understand the concept of the triple point of a substance, the combination of temperature and pressure that can result in a substance existing in all 3 states, but practically I always had trouble understanding it. I think this was because I’d take it to it’s logical conclusion, I.E. that essentially the substance would exist in all 3 states simultaneously something which seems impossible. Of course in practical terms this never occurs with whatever substance existing in one of those 3 states, with the added ability to quickly change to another one. Explaining the concept is one thing though, seeing it in motion makes everything far more clear:
The liquid in the video is called cyclohexane which has four distinct solid phases. I don’t think we’re seeing a transition between any of those specifically though, the temperatures required to meet them are below freezing and that appears to be room temperature, but this video does show how the triple point functions. Slight variations in pressure and temperature cause the substance to rapidly change from solid to a liquid and even straight to boiling (which you assume is producing gas). You probably wouldn’t want to reproduce this experiment as a demonstration to kids, cyclohexane is a derivative of benzene and likely carries the same nasty health effects, but you can do similar things as long as you have a vacuum pump.
The search for life beyond that of our planet is a complicated one. As it stands we only know of life arising in a particular way, one we can’t be sure isn’t unique in the universe. Still it’s the best model we have to go by and so when we search for life we look for all the same signs as we do for anywhere here on Earth. The one constant that binds all life on Earth is water and so that is why we search so fervently for it anywhere in the solar system. Surprisingly there are many places to find it but none are more spectacular than Saturn’s moon Enceladus.
Enceladus is a strange world, truly unlike anything else in our solar system. Its surface is incredibly young, mostly devoid of the numerous pockmarks that are common among other atmosphereless celestial bodies. This is because it’s in a constant state of change, it’s icy surface splitting and cracking open to reveal a new unsullied surface. Enceladus is like this because Saturn’s massive girth warps the tiny moon as it makes its orbit, generating incredible amounts of heat in the process. The same process is responsible for the amazing cryovolcanoes that dot its south pole, spewing forth tons of water per day into the depths of space. Whilst it’s easy to confirm that there’s liquid water somewhere on Enceladus (those cryovolcanoes aren’t magical water spouts) the question of where the reservoir is, if there even is one, has been the subject of much scientific study.
It has long been thought that Enceladus was host to a vast underground ocean although its specifics have always been up for debate. Unlike Europa which is thought to have a layer of liquid water underneath the ice (or a layer of “warmer” ice) the nature of Enceladus’ ocean was less clear. However data gathered by the Cassini spacecraft during its flybys of the moon in 2010~2012 show that it’s very likely that there’s a subsurface ocean below the area where the plumes originate. How they did this is quite incredible and showcases the amazing precision of the instruments we have up in space.
The measurements were made by using the radio communications between Cassini and Earth. These stay at a relatively fixed frequency and thus any changes in the craft’s speed will manifest themselves as slight Doppler Shifts in the frequency. This is the same principle behind how the sound of an approaching ambulance changes as it gets closer and farther away and it allows us to detect even the smallest changes in Cassini’s speed. As it turns out when Cassini flew over Enceladus’ south pole, which has a great big depression in it (meaning there’s less gravity at that point) the change in speed was far less than what we expected. What that means is there’s something more dense below the depression that’s making up for the lack of matter in the depression and, since water is more dense than ice, a giant hidden sea is a very plausible explanation.
There may be other explanations of course, like a giant deposit of heavy elements or just plain rock, however the fact that there’s water gushing up from that location gives more credence to the theory that it’s an ocean. The question now turns to nailing down some of the other variables, like how big it actually is and how the water gets to the surface, which I’m not entirely sure the Cassini craft is capable of determining. Still I wasn’t completely sure it was capable of doing this before today so I’m sure the scientists at NASA have some very interesting ideas about what comes next for Enceladus.
It’s late 2001 and I’ve finally managed to find a group of like minded people who enjoy computers, games and all things that I felt ashamed of liking for the better part of my teenage life. We’re gathered at a friend’s house to have a LAN as this was long before the time when broadband was a common thing in Australian households. As much as these gatherings were a hive for sharing ill-gotten files they were also the beginnings of my career in IT as often we’d be experimenting with the latest software just for laughs. It’s at this very gathering where I had my first encounter with the latest operating system from Microsoft, Windows XP, and little did I know that I’d still be encountering it for the next 13 years.
Today marks a day that we have known was coming for a long time but many have refused to accept: the day when Windows XP is no longer supported by Microsoft. You can still get support for Microsoft Security Essentials on Windows XP until July 14, 2015 but Microsoft will no longer be providing any updates, free or paid, to the aging operating system. For administrators like me it’s the ammunition we’ve been using for the better part of 2 years to get people to move away from the old operating system as nothing scares corporate customers more than the possibility of no support. Still though out of the total Windows market share XP still claims a staggering 27%, meaning almost 1 in every 3 Windows users is now on a system that won’t have any kind of official support. Many have criticised Microsoft for doing this but in all honesty it had to happen sometime or they’d never see the end of it.
The reason behind XP’s longevity, something which is usually unheard of in the high technology industry, can be almost wholly attributed to the utter dismal failure that Windows Vista was. Prior to that Microsoft customers were more than happy to go through the routine upgrade process every 3~5 years however the fact that Vista didn’t deliver on what it promised, coupled with it’s astoundingly bad reliability, meant that the vast majority of organisations got comfortable with Windows XP as their operating system. The time between XP and Windows 7 was long enough that the pain of moving forward became too great and many opted to wait until there was just no option left for them. My most recent project was a great example of this, migrating a large government department to Windows 7 from XP which only barely missed the deadline that was hit today.
This is the prime reason behind Microsoft’s recent change from a longer product cycle to one that’s based around rapid innovation. Whilst it’s true that Windows 8 is shaping up to be the Vista of this current product cycle, with Windows 7 adoption rates still outpacing it, the vast majority of the hard work will be done if users finally move to Windows 7. The upgrade paths from there are a whole lot more forgiving than coming from XP and moving from 8 to 8.1 takes about as much effort as installing a patch. I’m quietly hopeful that Windows 7 won’t become the next XP but at the same time I know how readily history can repeat itself.
So it’s without a heavy heart I say goodbye to Windows XP. It will not be missed by anyone in the industry as it was supposed to be dead and buried a long time ago and it was only through the stubbornness of the majority that it managed to stick around for as long as it did. I’m hoping for a much brighter future, one where Microsoft’s quickened pace of development is embraced and legacy systems are allowed to die the swift death that they so rightly deserve.
There’s an argument to be made that we should be in total control of everything that goes into our bodies and I support that idea to an extent. However when your decision can adversely impact the lives of others that’s when I support intervention which is why I wholly support compulsory vaccination. This also extends to my support of water fluoridation as, again, whilst there’s numerous arguments that can be made against it the fact that it will benefit so many at almost no risk to others means it’s a net positive for us as a whole. Of course this hasn’t stopped a vocal minority from claiming all sorts of horrific things happening due to water fluoridation the worst of which being that it’ll make you stupid.
A single article on Huffington Post usually wouldn’t warrant my attention, it’s not exactly known as the bastion of sound scientific reporting, but it came across my path not long after a similar post from a Facebook page called The Mind Unleashed claiming that fluoride in water lowered IQ significantly. Because I couldn’t help myself I spent a good couple hours tracking down the research and other articles relating to it. Just like most reporting on scientific discoveries this one is completely overblown and, when you dig into the details, doesn’t support the conclusions that many would draw from it.
I’d love to say that I was surprised by this but this isn’t my first rodeo with bullshit.
A review of water fluoridation studies done researchers at Harvard University concluded that whilst water fluoridation may affect IQ scores the levels that were detected in the study were at least 10 times higher than what’s found in artificially fluoridated water. Additionally the studies failed to control for other variables which are known to affect brain development and IQ scores like the fact that many of the studies were conducted in highly polluted areas in China. Funnily enough the control group in one of the studies were consuming water with similar levels of fluoridation to that of developed countries which shows pretty clearly that the current dosage levels work without the noted side effects.
On the flip side there’s a lot of research that shows water fluoridation reduces cavities in children and adults by a significant percentage, even in those who already have access to it through other means (like toothpaste or as an additive in other food staples). Indeed if you’ll allow me to get hand wavy for a bit there’s evidence to suggest that the average IQ has been trending upwards for the last hundred years or so called the Flynn effect. If fluoridation had a significant impact on IQ scores then we should’ve seen a harsh dip around 1960 when in fact we see the exact opposite. Now correlation does not equal causation but it’s a pretty good indicator that the negative isn’t true.
I could go on but the fact is that water fluoridation works incredibly well as a public health policy, greatly helping those who are at risk at developing tooth cavities and even those who’d consider themselves not needing it. Therefore removing it would cause harm to those who can least afford it to happen to them and that’s why bad science reporting like this needs to be exposed for what it is. I know I’m probably preaching to the choir here but I know how hard it can be to debate people who spout nonsense as fact and hope that you can use this as a reference rather than having to disappear down the research hole that I did.
Sometimes the things that happen after a review is penned are far more important than those that came before it. Diablo 3 is a prime example of this as whilst my initial impressions of the game were nothing short of amazement the tale of my experience after that is much more mixed. The challenge progression felt great, for a while, but once I hit Inferno the game shifted from being a conquerable challenge to an exercise in frustration. The auction house, initially a great source to give your character a quick boost, soon became the bane of my existance with all the items I needed far beyond my reach and the amount of griding required to get them far too high. It wasn’t long before I lost interest, alongside many of my long time Diablo fan friends. Blizzard was keenly aware of this however and the release of Diablo 3’s first expansion pack, Reaper of Souls, sets out to correct many of the missteps of its predecessor.
With the defeat of Diablo at the top of the crystal arch humanity was once again safe from his terror. However his essence was still captured in the black soulstone, unable to be destroyed even by the angels of heaven. Tyrael, now the mortal Aspect of Wisdom, has once again sought out the Horadrim to secret away the soulstone so that none may attempt to use it for their own purposes. However Malthael, the Archangel of Wisdom who had been lost ever since the destruction of the World Stone, had tracked the soulstone’s location. Whatever his plans are for it are not known but one thing is for sure, you, the Nephalem, are the only one who can stop him.
As you’d expect from an expansion pack Reaper of Souls adds a little more graphical flair to Blizzards’ flagship dungeon crawler although it’s nothing major like an overhaul of the graphics engine. The environments do feel like they have a lot more detail in them and the use of lighting and environmental effects is a lot more liberal, especially in the new areas. Still Diablo 3 is a game that’s meant to be fast paced so much of it is designed to run well without stutters or slow downs and with Blizzard’s reputation of being the low poly kings this ensures that the visuals are still on par with other current generation titles.
There have been some major changes to the core game play of Diablo 3 in Reaper of Souls, the vast majority of which have been aimed directly at addressing concerns that the community raised. The auction house is gone (both of it’s incarnations), the loot system revamped in a massive update called Loot 2.0 and the end game changed significantly adding in a new mode to replace the previous boss run meta that was the norm since Diablo 2. Additionally all the classes have had significant work done on their skills in order to make more of them viable for both end game loot farming as well as during your initial levelling experience. Suffice to say that whilst Reaper of Souls might only bring an additional act’s worth of content it adds an incredible amount of replayability, enough so that this feels like the game Blizzard should have released 2 years ago.
I actually jumped back onto Diablo 3 prior to the release of Reaper of Souls in order to try out the new Loot 2.0 system. Suffice to say I was very impressed as it only took me a couple hours to move from my less-than-stellar auction house purchased Inferno gear to a new set that was much more suited to my playstyle. It also didn’t take long for me to pick up a couple legendaries that completely changed the way my character was built, tempting me to try out builds that would have otherwise been completely unviable. Indeed even without those pieces of gear the various builds I experimented with all felt viable, a highly refreshing change to what I had to do previously.
Levels came thick and fast with my monk being able to reach 70 after a few nights worth of play. Indeed the levelling was so fast that I had pretty much reached level 70 before facing Malthael, only requiring a slight detour for the last push. The same can be said for Paragon levels that you’ll continue to amass after you reach max level, especially if you’re doing bounties or rifts often. The extra levels don’t add too much to the classes although the addition of another passive skill slot at max level does open up a lot of opportunities for builds that might not have been viable previously. The new monk skill, epiphany, is quite interesting although my current gear selection isn’t as effective with it as other builds. Whilst this might be disappointing to some (typically the new skills added in tend to be overpowered) I feel it’s a show of good design as the new skill adds variation whilst not being so powerful that its use is required.
The new way of running end game content is an obvious attempt to shift the current meta of boss runs for items to a more varied approach, incorporating a number of different types of runs that will result in a certain number of legendaries per hour. The first one is called Adventure Mode and is unlocked after completing the campaign through once. In this mode you’re given a series of bounties, usually things like “Clear out all enemies in the Den of Evil” or “Kill this act boss”, and for each of the ones you complete you’ll receive some XP and gold. Complete all of them within one act and you’ll receive a cache from Tyrael that contains a number of items, gems and health pots. This is in addition to any items that might drop along the way which will usually fill your inventory once for every 2 bounties completed. There’s also Nephalem Rifts which are randomly generated dungeons that require you kill a number of enemies before a boss will spawn and the Infernal Machines which pit you against super versions of act minibosses with a chance to drop legendary crafting materials.
The addition of the mystic, along with the minor tweaks to the crafting system, are welcome changes. The mystic allows you to reroll one stat on a piece of gear to another stat, making more pieces of gear viable. The costs of doing so are a little on the extreme side, especially for legendaries which all require a disenchanted legendary, but it can be worth it when you’re trying to min/max your way to victory. The limitation of only rerolling one stat is a little frustrating sometimes as you’ll often come across gear that’s got 2 junk stats on it but is otherwise fine but I can understand why this limitation is put in place. I’d probably complain less if crafting was actually worthwhile as currently the costs seem to heavily outweigh the chances of creating something that you’d use.
For the most part all of this adds up to a very enjoyable experience however I’d be lying if I said it didn’t start to feel a little grindy after a certain point. Sure my character is decked out in about half legendaries, some of them quite amazing, but the quest for items that improve my character has become somewhat arduous. I see as many legendaries drop as the next guy but even with my small collection I already have duplicates (quite irritating when you consider you can’t equip 2 of the same legendary weapon) and I’ve yet to see a solid upgrade in the last few days of play. It’s hard to fault Reaper of Souls specifically for this, it’s just the uncaring wrath of the random number generator, but grinding without the guaranteed reward of an upgrade at the end of it does sap a lot of the fun out of the experience. Now that I’ve said that I’ll probably do one run and get 3 upgrades in a row and all will be right in the world.
Diablo 3: Reaper of Souls is the game Blizzard should have released 2 years ago as it has managed to capture the enduring attention of so many of my Diablo fan friends where the original failed to do so. The revamps to the talent system, loot and addition of the mystic all add up to make the experience far more enjoyable and rewarding, removing some of the reliance on good rolls to give you the stats you require. Adventure mode is the end game that many were seeking originally, something that provides a bit more flavour to the traditional boss runs of yore. Of course this doesn’t absolve you from the grind completely and, if I’m honest, this will likely be the thing that drives me away from playing Reaper of Souls. Still it’s enough that I feel that Diablo 3 will resurface as one of the LAN games of choice as it’s a lot of fun to blast through a couple bounties or rifts with a close bunch of friends.
Diablo III: Reaper of Souls is available on PC right now for $49.95. Total play time was approximately 15 hours reaching Paragon level 56.
It’s fascinating to think about how unique our perception of the world is. We like to think that everyone experiences the world in the same way we do but we all have subtle differences that influences the way we perceive the world. I for instance have partial red-green colorblindness which affects my ability to distinguish between darker shades of certain colours. The difference for me is subtle but for others who suffer from more pronounced colorblindness the different can be extremely drastic, completely changing how they view the world.
Similarly for those who are deaf or hearing impaired the world would seem like a very different place to them, bereft of all the noises and sounds we think are commonplace. For some there are treatment options available, like cochlear implants, and for the longest time I thought that the sounds that users of those devices were the same as the ones you and I can hear. As it turns out their auditory world could not be more different and the simulation below shows just how different it is:
I had read a little while ago that music sounded completely alien to those who had received cochlear implants but actually hearing what it might sound like was actually quite shocking. The improvements that came through with the extra channels were impressive but I had a hard time recognizing the elements of the music, even after I heard the original clip. I understand that the main function of cochlear implants isn’t music (they are primarily aimed at speech) but the differences were so stark that it was, to be honest, quite shocking.
Thankfully it does seem like there are vast improvements being made in this area, to the point where users claim that music is enjoyable for them. Hopefully with time we’ll be able to improve even further so one day the auditory world of those with cochlear implants won’t be much different from ours.
Whilst the debate among the space enthusiast community still rages about what the next target for human exploration should be those with the capability seem to have already made a decision: we’re going to Mars. NASA has committed to getting astronauts there some time around 2030 and SpaceX’s founder and CEO, Elon Musk, has long held the dream that he’d be retiring on Mars. There’s also the Mars One which, to my surprise, is still going and garnering attention worldwide even here in my home country. The lack of a return mission to the Moon does raise some questions about the technology that will be used as we don’t have any craft capable of going past low earth orbit, not since the Apollo program ended almost half a century ago.
NASA has been working on a new crew capsule for some time now, dubbed the Orion. Initially this was part of the planned 2020 mission to return to the Moon however the majority of that was scrapped in favour of going directly to Mars. The capsule and the revised launch system were retained however and will form the basis of NASA’s future manned space missions. However if the Moon is no longer the goal for this craft and it’s end goal will be long duration flight there’s a lot of testing that needs to be done before we send one of them to Mars. Interestingly NASA has gone for an incredibly ambitious mission to put the Orion’s long duration flight capabilities to the test: an asteroid capture and analysis mission.
There’s currently two mission profiles being considered, both of them seeming like something straight out of science fiction. The first (and I’ll guess least likely of the two) is a robotic craft will make its way to a large asteroid, break a chunk of it off and then bring it back into orbit around the moon. The second would be a straight up asteroid capture with the craft grabbing an asteroid in its entirety (it would be small, about 7m or so in diameter) and, again, putting it into lunar orbit. Then once the asteroid is in a stable orbit NASA will send crew to it in an Orion capsule to study it, testing out some of the long duration capabilities as well as other rudimentary space activities like EVAs.
Such a mission is actually quite feasible (at least the latter profile) from a technical perspective. Pretty much all the technology required to capture an asteroid of that size is available today and there’s already 6 candidate asteroids identified. The main issue I see with it is time as just getting to the asteroid is planned to take at least 4 years with another 2 to 6 required for it to make the trip back. That means if the mission were to launch today it could potentially take up to 2024 before it returns to us which doesn’t leave a lot of time for NASA to test out the Orion capsule on it, This could be sped up considerably by changing it’s launch profile to include a second stage rocket to boost it rather than relying on the ion thrusters to achieve escape velocity but that would come with additional expense. There’s also the possibility of foregoing the robotic part of this mission completely and just sending humans although that poses just as many challenges as going straight to mars.
I’m glad to see NASA making a return to missions like these, ones that truly push the envelop of humanity’s space capabilities. It’s going to be interesting to see how the mission develops as there’s lots of different variables that need to be sorted out, some that will change the mission dramatically. Still the thought of us being able to capture an asteroid, bring it into lunar orbit and then send humans to study it is just an incredible thing to think about and I truly hope NASA sees this one through to fruition.
