can you exchange a queen for two rooks in chess???

just caught a reference and searched it mightily but found only pages on the value of either
nothing about the mechanics of an exchange

anybody?

Certainly...but is it worth it?...that is the question.
This is in reference to taking your opponent's rooks, at the cost of losing your queen.

James Webb Space Telescope's Smooth Launch Extended Its Life Expectancy, NASA Says

The James Webb Space Telescope should be able to remain in orbit for more than 10 years, thanks to a fuel-efficient launch on Christmas Day, according to NASA. From a report:

The telescope was carried aboard the Arianespace Ariane 5. Despite two brief midcourse corrections, its launch used less propellant than initially expected. That will allow the $10 billion observatory "science operations in orbit for significantly more than a 10-year science lifetime," the US space agency said in a release on Wednesday The first midcourse correction was a relatively minor, 65-minute post-launch burn, which bumped up the telescope's speed by approximately 45 miles per hour. Another smaller correction on Dec. 27 added an additional 6.3 mph. That added boost also allowed the JWST's solar array to unfold about a minute and a half after it separated from the Ariane 5, just 29 minutes after launch. The array was coded to automatically deploy either when the observatory reached a certain altitude or 33 minutes after launch, whichever came first.

thanks dill!

in the weeks leading up to launch nasa said the craft has to preform over 300 mission critical operations, but it unfolded only 30 minutes after launch and that was the big one as i was concerned. after launch and escape velocity...

A YouTuber who goes by the name of Buildzoid on the Actually Hardcore Overlocking channel has figured out that a backward capacitor on the Asus ROG Maximus Z690 Hero motherboard is causing it to melt down, according to a report by Tom's Hardware. From a report:
Asus has since acknowledged the issue in a post on its site and plans on issuing replacements to customers with affected motherboards. Problems with the Z690 Hero motherboard started turning up on the Asus support forum, as well as on Reddit, and the issues experienced by users are pretty much identical. As noted by Tom's Hardware, users reported that their motherboards started smoking in the same spot: the two MOSFETs (metal-oxide-semiconductor field-effect transistor) next to the DIMM slots and the Q-code reader. In a video on his channel, Buildzoid diagnoses the issue using only the pictures posted to support forums and on Reddit, attributing the Z690 Hero's failure to the backward capacitor installed next to the MOSFETs, not the MOSFETs themselves. Buildzoid looks closely at the images of the motherboard, pointing out that the text on the capacitor is actually upside down, a potential sign that it's installed incorrectly. As Tom's Hardware mentions, a reversed capacitor results in reversed polarity, causing the MOSFETs to malfunction and burn up.

"For the first time, astronomers were able to observe the death throes of a red supergiant star in real time," writes Slashdot reader quonset from a report via CNN. "The fortuitous event came about when astronomers were first alerted in the summer of 2020 by a release of bright radiation detected by the University of Hawaii Institute for Astronomy Pan-STARRS telescope on Maui's Haleakal. Then, In the fall, astronomers witnessed a supernova form in the same spot." From the report:
Before they go out in a blaze of glory, some stars experience violent eruptions or release glowing hot layers of gas. Until astronomers witnessed this event, they believed that red supergiants were relatively quiet before exploding into a supernova or collapsing into a dense neutron star. Instead, scientists watched the star self-destruct in dramatic fashion before collapsing in a type II supernova. This star death is the rapid collapse and violent explosion of a massive star after it has burned through the hydrogen, helium and other elements in its core. All that remains is the star's iron, but iron can't fuse so the star will run out of energy. When that happens, the iron collapses and causes the supernova. A study detailing these findings published Thursday in The Astrophysical Journal.

"It's like watching a ticking time bomb," said senior study author Raffaella Margutti, an associate professor of astronomy and astrophysics at UC Berkeley, in a statement. "We've never confirmed such violent activity in a dying red supergiant star where we see it produce such a luminous emission, then collapse and combust, until now." Some of these massive stars likely experience consequential internal changes that cause the tumultuous release of gas before they die, the finding has shown.
