Just a neat little animation showing the apogee and perigee (the moon’s equivalent to aphelion and perihelion) of the moon as viewed from Earth. Also it reminds me of Majora’s Mask.

This is a tumblelog, kinda like a blog but with short-form, mixed-media posts with stuff I like. Scroll down a bit to start reading, or a bit more to read more about me.

Squareという会社のモバイル決済サービス「カードケース」が注目されているそうだ。日本でのモバイル決済は、ほぼFelicaを用いた電子マネーが中心だが、「カードケース」は非常にユニークだ。スマートフォンを操作したり読み取り装置にかざしたりする必要が無い。レジで名前を名乗るだけで支払いが済んでしまうのだ。その仕組みはこうだ。利用者は、スマートフォンにカードケースのアプリをインストールする[itunes (USのみ)]。そして、カードケースで支払いができるお店ではレジで名前を告げる。レジ係はiPadで店舗用のアプリを使い、名前と顔写真を確認。これで支払いが完了する。レシートはスマートフォンに送られてくる。カードケースのアプリ(iPhoneとAndroid用がある)はジオフェンシング (Geo-fence)技術を使っており、アプリは所定のエリア内に入ると、システムが自動的に認識するようになるのだ。セキュリティ対策としては、利用者がカードケースで自動的な支払いを行うかを店舗ごとに設定する必要があり、店舗から100フィート以内にそのスマートフォンが存在しないとこのサービスは利用できない。また、本人確認を顔写真でも行っており、買い物が行われると直ちに本人のスマートフォンに通知が行く。デビット・カークパトリック氏も、注目している企業のようだ[techcrunch]。Squareのビデオを見ると、あまりの簡単さにびっくりしてしまう。

Saturn’s largest moon, Titan, is in the background of the image, and the moon’s north polar hood is clearly visible. See PIA08137 to learn more about that feature on Titan (3,200 miles, or 5,150 kilometers across). Next, the wispy terrain on the trailing hemisphere of Dione (698 miles, or 1,123 kilometers across) can be seen on that moon which appears just above the rings at the center of the image. See PIA10560 and PIA06163 to learn more about Dione’s wisps. Saturn’s small moon Pandora (50 miles, or 81 kilometers across) orbits beyond the rings on the right of the image. Finally, Pan (17 miles, or 28 kilometers across) can be seen in the Encke Gap of the A ring on the left of the image.

WHOA-LGERS Milwaukee-based photographer Jack Long uses high-speed photography to capture the moment splashes are made in cups of coffee. He won’t reveal exactly how his technique works, except to say that the technique employs “short-duration flash lighting.” And perhaps not using decaf.

The Voyager Golden Record
The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecraft, which were launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. The Voyager spacecraft are not heading towards any particular star, but Voyager 1 will be within 1.6 light years of the star AC+79 3888 in the Ophiuchus constellation in about 40,000 years.[1]
As the probes are extremely small compared to the vastness of interstellar space, the probability of a space faring civilization encountering them is very small, especially since the probes will eventually stop emitting any kind of electromagnetic radiation. If they are ever found by an alien species, it will most likely be far in the future as the nearest star on Voyager 1’s trajectory will only be reached in 40,000 years.
Carl Sagan noted that “The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this ‘bottle’ into the cosmic ‘ocean’ says something very hopeful about life on this planet.”[2] Thus the record is best seen as a time capsule or a symbolic statement rather than a serious attempt to communicate with extraterrestrial life.](http://29.media.tumblr.com/tumblr_lw46fji5pY1r2p9x3o1_400.jpg)
