I have 2 socks laying on my dresser now and neither is the pair to the other. They are each waiting for their respective better halves to return. 🤭

place i used to work made the D2 calibration light sources(lamps) for the spectrometer

Comet makes a pit stop. Must be a galactic Flying J in that debris field.

I'm going to apply for a grant to study this. I'm not greedy, say $100,000. I'll call it... ah... “Disappearing Foot Wear Apparel Phenomenon''/ A Thesis''. (If I get the dough I'll send you,.. $10, 000. Sound ok?)

[jmacusa]

Mmmm. Yes. Sound observation. Might I suggest, as I intend to do and apply for a big government grant to study the problem?

How can we be an advanced civilization if socks in a house hold appliance can defy the laws of physics and leave and enter other dimensions there by over coming the time/space continuum?

[MachIV]

LOL.

Thanks for the info

James Webb Space Telescope has such sensitive infrared capability it could easily detect a bumble bee on the moon. Each one of its 18 hexagonal mirrors have are so precise that if you stretched them out over the surface of the U.S. there would be only 3 inches deviation over its surface. They are made of Beryllium, a metal that is lightweight and strong that will never go out of shape. Each mirror must be aligned with each other to the nano meter. To do that they have computer controlled devices to align each mirror out in space. There is no way its mirror be out of focus like the Hubble.

There is so much that had to be invented for the sensors and other elements of the system, this telescope will be an incredible achievement for science.

The telescope has functions that had to be invented. The technology had to be most precise and that’s why the instrument costs so much. The infrared sensor system is so precise it will be able to detect a bumblebee from the distance of the earth to the moon. Its infrared sensors have to be cooled to -364 degrees F. Another instrument, the Mid Infrared Instrument has to be cooled to -446.8 degrees F. This entire system by itself costs a $Billion. The Beryllium mirrors must have cost of fortune due to the rare earth nature of Beryllium. The camera system and its cooling systems had to be invented (pumps, because they vibrate had to be designed not to vibrate). Its cost is a $Billion.

The 18 hexagonal mirrors had to be shaped to the nano meter. If one of them stretched over the entire U.S. it would only deviate 3 inches. Each mirror can be aligned by special actuators to the nano meter by computer. The entire array was engineered to fold to fit inside the launch vehicle.

The telescope has been completed and it is undergoing testing. Nothing before has been made as complicated as this instrument. Because it does not have the problems of viewing the images withing earth’s atmosphere, so it will get images much sharper than ever received, back into the history of the universe to the first light. Everything has to work perfectly so it does.

#7. re “why, when you put a pair of socks into the dryer only one ever comes out”.

“SHRINKAGE”!!!!

[jmacusa]

Boy. That’ some shrinkage. Had I known this years ago I’d have stuck my pesky kid brother in there.
