Andrew McCarthy combined 50,000 images taken from his telescope and camera in Sacramento, California into a single, breathtakingly detailed image.
A recent discovery based on observations by the ESA/NASA Solar and Heliospheric Observatory, SOHO, shows that the gaseous layer that wraps around Earth reaches up to 630 000 km away, or 50 times the diameter of our planet.
“The Moon flies through Earth’s atmosphere,” says Igor Baliukin of Russia’s Space Research Institute, lead author of the paper presenting the results.
How cool is that?
Scott B. Weingart goes into great detail as he takes us along on the journey of a text message. How detailed? Here’s a bit from the part about typing the message on a phone’s screen:
With each tap, a small electrical current passes from the screen to her hand. Because electricity flows easily through human bodies, sensors on the phone register a change in voltage wherever her thumb presses against the screen. But the world is messy, and the phone senses random fluctuations in voltage across the rest of the screen, too, so an algorithm determines the biggest, thumbiest-looking voltage fluctuations and assumes that’s where she intended to press.
So she starts tap-tap-tapping on the keyboard, one letter at a time.
A surprisingly enjoyable read considering how deep into technical details it goes.
This is a great little four-minute video that explains what the heck those floaty things are.
Sometimes, against a uniform, bright background such as a clear sky or a blank computer screen, you might see things floating across your field of vision. What are these moving objects, and how are you seeing them? Michael Mauser explains the visual phenomenon that is floaters.
In the 1970’s the suspender ropes of the Golden Gate Bridge were replaced. Some of the old ropes were saved by this company and turned into various collectable (and expensive!) items.
Strands of History produces high quality, hand-crafted luxury items fabricated from the original Golden Gate Bridge vertical suspender ropes. We design and fabricate these authentic historical suspender ropes into limited edition or completely customized decorative and functional pieces, including mementos, furniture, lighting, architectural pieces and accents, artwork and sculpture. Because there is a limited quantity of these suspender ropes from the 1930’s, when you acquire one of these genuine pieces of Bay Area history, you’re investing in an asset that will be passed from generation to generation.
That coffee table on their front page is quite stunning, but for $18,500 I would hope for something that would take my breath away.
