This is a very nice argument!

Our senses are still only tuned in to detect portions of "reality" that are relevant to life on earth. For example, our eyes detect the band of EM radiation most useful during daytime on Earth. But even though are eyes are narrow band and highly non-linear sensors, they (+our other equally flawed senses) have served us pretty well as far as understanding the true nature of EM waves.

I guess my point is that our senses still aren't evolving to detect reality in some sort of true pure mathematical sense.

So the Sell/Check/Recycle model only requires 33% of the labor compared to the Check only model. The author suggests that this means tripling production would be possible, but that depends on QA being the factories bottleneck. If QA isn't the bottleneck, than you might as well fire 2/3 of Quinn's QA workers. Hooray, the computer didn't take my job, but it took the jobs of the guy to my right and the gal to my left.

Physics experiments have ruled theories like this out. They can put a very very small upper bound on how much the constants can change over a volume the size of the universe, and over the lifetime of the universe.

So then why is it important? What is the argument for encrypting all web traffic? Does it act as a sort of camouflage for the actually important encrypted traffic?

Ignorant question: If they are making getting a certificate easy for everyone, what is to stop "bad guys" from getting certificates for their sketchy sites? I usually look to the green "https" in my uri bar for reassurance when I'm on an unusual site.

There is at least one fundamental truth: obesity is on the rise. Why?

I think it is safe to assume that a rapid change in the human genome is not responsible for skyrocketing obesity rates around the world. From what I have read it seems that dietary shifts towards more processed and simple-carbohydrate rich food are the main culprit. Increasingly sedentary lifestyles are accomplices.

These effects are on a statistical and societal level. Also, they don't imply that and individual can just change their diet and easily loose weight. It is possible once someone gains weight their body irreversibly changes so that losing weight becomes much more difficult (I mean irreversible to imply hysteresis, not impossibility).

Anything that has an energy can be turned into a temperature by dividing by the Boltzman constant k_b (units: Joules/Kelvin).

The meaning of that temperature can be hard to interpret, though. Temperatures make the most sense when you are thinking about thermodynamics, not when you consider a single isolated particle.

Epic Systems (digital healthcare records) employs 5,000 people just outside Madison, WI. Soon to be 10,000 according to their roadmap. I wouldn't be surprised if other corporations looking to hire gobs of college grads start popping up (or already have popped up) near other small midwest cities.

This is a misleading headline! This 'hard drive' needs to be in a superconducting magnet and held at 2K. I'm not aware of any desktop chassis that comes with a a cryostat...

Imagine being inside of a closed box like an elevator. Without leaving the box there is no way to tell the difference from being in free fall towards Earth versus floating in interstellar space. Therefor, general relativity take the perspective that gravity is a fictitious force (like centrifugal force) that arises from the shape of spacetime.

This is basic science. It doesn't need to be directly useful. The possibility of creating lifeforms that use different base pairs in their DNA is fascinating. It has implications about how similar or dissimilar life that evolved separately elsewhere in the universe could be. I hope they keep up the good work!
