Picture Earth at the center of a frame. The planet looks unassuming, a fleck, its blue-and-white marbling stark against a black interstellar backdrop. Yet the image likely evokes some reaction.
Now imagine seeing this view from space.
Astronauts who experience Earth from orbit often report feelings of awe and wonder, of being transformed by what they describe as the magic such a perspective brings. This phenomenon is called the “overview effect,” and researchers from the University of Pennsylvania’s Positive Psychology Center are studying it to better understand the emotions astronauts commonly recount.
Penn research fellows David Yaden and Johannes Eichstaedt, and intern Jonathan Iwry, with colleagues from Thomas Jefferson University, the University of Houston and others, have several goals with this work: to look at implications for space flight as the aeronautical community heads toward years-long missions to places like Mars, and to understand how to induce a similar sensation for non-astronauts.

In 1930, German theoretical physicist Werner Heisenberg came up with a thought experiment, now known as Heisenberg’s microscope, to try to show why it’s impossible to measure an atom’s location with unlimited precision. He imagined trying to measure the position of something like an atom by shooting light at it.
Light travels as a wave, and Heisenberg knew that different wavelengths could give you different degrees of confidence when used to measure where something is in space. Short wavelengths can give a more precise measurement than long ones, so you’d want to use light with a tiny wavelength to measure where an atom is, since atoms are really small. But there’s a problem: light also carries momentum, and short wavelengths carry more momentum than long ones.
That means if you use light with a short wavelength to find the atom, you’ll hit the atom with all of that momentum, and that kicks it around and risks completely changing its location (and other properties) in the process. Use longer wavelengths, and you’ll move the atom less, but you’ll also be more uncertain about your measurement.

というわけで、久々に洋ゲーワンドロ深夜のお絵かき一発勝負やってみました\(^o^)/
お題は「ヒーロー/ヒロイン」でした。
火炎放射器や背中にしょってる何かが相変わらずうろ覚えクオリティですが許してね!
さりげなくデジ絵を描くのに抵抗がついたので、これからは心置きなくパソコンでもお絵かきしようと思います。
でもパソコンで線画はまだ遠そうだな…

You’ve seen police cars, but what about a police truck? They’re not very well suited to high-speed chases, but pickup trucks can still be useful to law enforcement agencies. They can carry plenty of gear, and go where traditional sedans can’t.
