Near and far infrared, ultraviolet, x-rays, gamma rays -- there are lots of photons out there. Hubble has many sensors[0], so many of the images taken are from outside the relatively small portion of the spectrum that humans can see and the

See the table on page one of chapter 5 (page 51 in the pdf) of http://comptroller.defense.gov/Portals/45/Documents/defbudge... Actual expenses in 2012 show that military pay and benefits accounts for 34.6% of

I was trying to illustrate that trivializing the complexity of human-level intelligence in AI is like saying humans are "just" a collection of molecules. It's not that it's impossible, it's just hilariously more com

I don't mean to be snarky, but it can be illuminating to change your statement just a little bit: >>Why wouldn't there be any possibility of making artificial humans? We are just a manifestation of a physical system of bonds

"Wrong" is a strong word. There are compromises in every design. As pointed out by another poster, accurate pole alignment will be the dominant source of error for any reasonably accurate barn door. The short focal lengths, wide f

It depends a lot on the problem domain. Sometimes rapid prototyping is a useful tool, but the benefits rapidly diminish in the face of complexity. In my experience with moderately complicated scientific and mathematical software, there isn&

"Suffer" may be a bit overstated - if he was isolated, it was largely self-imposed; and if he was persecuted, it may have had more to do with his behavior than beliefs.[1] Best to think of Newton as the real-life "House"

By the modern understanding of the word "academic" it is more like a skilled trade.

That's one of the down sides to napkin math. I posted a follow up on another comment. Including some of the efficiencies leads to a net increase of about 20% in electricity usage.

Under those conditions, converting all vehicles to electric would increase net electricity usage by ~20%. (Better than 100%!) Eliminating gasoline refining would reduce the needed electricity by ~850 billion kWh / year, and the improve

You are correct - it assumes total conversion, but the numbers don't change if you project some ramp for the transition. A more reasonable assumption for charging is that it will take place wherever electric vehicles are parked, regard

Napkin math supports your concerns. - The US used 134.51 billion gallons of gas in 2013.[1] - There are ~33 kWh/gal in gasoline [2] 134.51e9 gal x 33 kWh / gal = 4.44e12 kWh (4.44 trillion kWh / year) - The US used a total of

It looks like the OSU program requires a bachelors degree in another subject and the UMUC program is $60,000 in tuition (for out of state students; $32,000 in state) - which is about 3x what I paid for my undergrad tuition 5 years ago. Not

I'm in it and it's awesome. They're doing some really cool things pushing forward the tech for online delivery and course management. And I'm happy to say that it is every bit as rigorous as you would expect from a Top 1

Sounds like "no true Scotsman", to me. Women have faced, and continue to face, challenges in tech circles. It's hard to make progress because the first step is admitting you have a problem, and it's easy for the tech com

`make` allocates and initializes `a`, setting it to nil effectively uninitializes the variable. See below, where I declare `c`, but don't initialize it. From the Golang spec, http://golang.org/ref/spec#Map_types ,
