Video of liquid gallium alloying with aluminum, making it no stronger than wet cardboard.

I've just spent the last 20 minutes watching the videos on that guy's Youtube channel.

I feel like I should have taken more advantage of the opportunities to just screw around like that in grad school...especially with the unfettered access to as much liquid nitrogen as my heart desired, and plenty of late nights in lab with few people around to raise "safety concerns".

We had one cryo experiment in the whole of my EE master's program, but I didn't get to do it :(

With regard to photos of other planets, etc.

When I see photos of Mars, for example, I would like to know how the image has been altered, if at all.  Of course, there is no such thing as "unaltered" since many images contain non-visible wavelengths, but it would be interesting to know whether an image is displayed as the human eye would see it.

That can only end in success and will result in millions of tons of methane not being released into the atmosphere. We will also be able to eat legitimate meat once humans start travelling to Mars.

I'm sure uneducated/uniformed people will still argue that you are eating a living being because the cells are growing and reproducing... completely unaware of the fact that it's no different than what's going on in a fruit or vegetable.

Yes, it is.

And is more or less the solution to having a meat supply in space. It may arguably end up being one of humankinds' greatest achievements,

Yes, if it comes to that. It may take some time before we actually go colonising other planets (a lot of time), but test tube meat would be a #1 solution for at least part of the food problems.

45 minutes strapped in a tube you can't stand up in? Hmm, no.

How do you take a leak inn those things? Or, what happens if somebody has a claustrophobic attack?

Nah. Any means of transportation needs a fast way of getting out. In a car you pull over, in trains and planes you get out of the seat and go to the bathroom.
Technically, I also found his solution for earthquakes rather dismissive. At those speeds even the tiniest shift gets magnified.

I would definitely get claustrophobic in that thing.
It doesn't look like it would fit any decent amount of luggage either (unless I skipped some part where it mentions storage), not to mention that people are getting larger, so I can only imagine how much worse that would be. And I hope it has a good air system, because imagine being stuck in an enclosed space with some stinky dude.

Seems like a lot of infrastructure for something with many potential limitations compared to other transportation methods.

Ah yeah, it is mentioned in the text that there would be a luggage compartment in either the front/rear of the thing, with a luggage limit of 2 bags per person, no more than 50kg/110lb in total. I was judging by the diagrams when I did my initial skim.

Iv think we should rather focus in reducing the number of people traveling from coast to coast for no purpose other than to present some slides in front of a few people.

Funny you say that. My dad was just bitching about this last weekend. Last week, he flew to California and back (we are in CT) in less than a 24 hour period, just so he could attend a 3 hour meeting with some higher-ups.

Absurd.  Last month I had no less than 10 people fly here for 3 days from 3 different parts of the country to view a presentation that I could have easily done through webex or something.  Each one, no doubt, had their own hotel room and rental car.  Even funnier, is that some were returning home for a few days only to repeat this process elsewhere in the country.

There is value in meeting with people face-to-face in these meetings, but it usually doesn't offset the expense of gathering all these people.

My most absurd trip was a two-leg flight to San Antonio (leaving from Boston) with a coworker. Took about 6 hours flight or so to get down there, checked into hotel. Got up next morning, drove to army base to demo our software (which runs on Android phones). Arrive at the army base, sergeant greets us, takes our phones and tells us we can't stay on the base because we're not cleared. So, we drive back to the hotel, and fly back to Boston the next day.
Essentially, we were FedEx. Six man-days wasted on top.

The fallibility of memory gains traction. 

In New Jersey recently, the supreme court required jurors to be educated on the fallibility of memory as a standard procedure.

http://www.nature.com/news/evidence-based-justice-corrupted-memory-1.13543

With regard to questioning of eye-witnesses, a psychologist “realized that these questions were conveying information... I began to think of it as a process of memory contamination, and we eventually called it the misinformation effect.”  The wording of the questions has a large effect on the response and recall of memories.

Great documentary on history of man's mastery of the cold; beginning with the first technical air conditioner by blowing air over jars of ice to the modern day studies in super conductivity.
