They could improve its reputation by changing its name from 'Microsoft Internet Explorer' to 'Blackwater Internet Explorer'.
The original owners of 'Blackwater' are also frantically doing name-scrubs, so the name is currently unoccupied. (Blackwater --> Xe (2009-2011) --> Academi (2011-2014 )--> Constellis (2014-whenever people catch on to the new name).)
There are two main imaging techniques that work in moderate-energy gamma-rays: Coded Aperture which use a shadow mask; and Compton Imaging.
According to this article the camera uses Compton Imaging. In this technique you look at gamma rays that scatter off of one detector and into another. Each detector tells you where the interaction occurred and how much energy was deposited. From this information, you can derive for each gamma ray that it came from somewhere on a hollow cone (with its tip at the first interaction point.) If you detect many gamma rays you can look at where the cones intersect, and that's where the gammas are coming from.
How often have you heard of people who are lost in the woods/at sea, and who could have called for help if they had cell phone connectivity?
They could fly one of these as part of a search. Even if the owner isn't actively using the phone, the drone could detect the electronic serial number of each phone in its coverage area and match it against the lost person's phone.
If it is 53 cm instead of 5 feet, then scaling from the video is off by a factor of (5 feet/53 cm)^3 = 24 and his 4 bbarrels per second becomes 15 thousand barrels per day, assuming he only made that one mistake.
This is not good, but it is closer to the mainstream media than to the Revelation-quoting Alabaman.
The most ecologically sound place to put people is underground. The dead don't reproduce (though, surprisingly, their number increase every day) and they don't use energy, food, or other resources.
The energy released was mind-numbing: in one-fifth of a second, this supercharged magnetic neutron star blasted out as much energy as the Sun does in 250,000 years!"
There's no way for me to get my head around these numbers to "truly" feel it. What methods can you use to visualize such extreme numbers?
A fifth of a second is about the time it takes to blink. It's about 12 frames of a 720P HD video signal.
Fact: Every year, the temperature rose on average 0.01K or 0.0039 percent.
Fact: Temperature differences of less than 0.01 K require very sensitive equipment to be measured correctly.

Let's imagine that out of 73000 temperature readings only 3 values were only 1 degree Celsius off. The person reading the temperature scale made an error and incorrectly reported 21 degrees when the true daily average was 20 degrees.
If we have 3 erroneous readings out of 73000, the error is 50% higher than the assumed increase in global temperature.
Fact: 3 measurements out of 73000 being 1 degree off is an error of 0.00004 degrees. This is 1 day's worth of global warming.
If we thought we were able to predict when a specific global warming event would occur, and we we were actually wrong by an entire day, then obviously global warming is a crock.
The neutrinos from a core collapse supernova would be lethal to humans at the distance of Jupiter. Any given neutrino has very little chance of hitting interacting with normal density matter it passes through, but there are a LOT of neutrinos: about 0.05 solar masses of them.
Furthermore, they are the first things that escape from the core (apart from gravitational waves) since they move at near-lightspeed and have very little chance of interacting with the envelope of the star. The big flashy special effects are driven by the shockwave from the core reaching the surface, and that takes hours. So if you were at the distance of Jupiter, you would have time to die from neutrino effects before the blast hit you.
Admittedly, Betelgeuse is somewhat further away than Jupiter, and the only neutrino effects are likely to be a lot of very excited astrophysicists. But both Jupiter and Betelgeuse are much closer than 99.9999999999999999999% of the Universe, and much further away than everyone you've ever met, so the distance scales aren't that different.

Around 1980, there was a program called SPIKE, which was a virtual keypunch. It put an image of a punch card up on the screen (character graphics on a Z-100). As you typed, it wrote the characters (uppercase) at the top of the card, and blacked out the appropriate squares.
It had a mode to do blind typing (not all keypunches printed the characters at the top of the card--that cost extra). It also had a 'dropdeck' command to shuffle the lines of your file.

This immediately fails because masses less than the Planck mass are affected by gravity.
Examples of varying familiarity (to physicists) include the drops in the Millikan Oil Drop Experiment, Bose Einstein Condensates, and slow neutrons.
How about two identical Vela satellites stacked together without a frame.
