It's one of the pillars of Stoic philosophy. Why worry about things you have no control over?

[@EnthalpyAndEntropy]

@@rkf053fitz two reasons. First, a lot of folks lack the wisdom to know they don't have control over certain things, especially now in the US. Furthermore, even if ego and hubris aren't a problem, anxiety disorders are a thing. Second, as an engineer, I worry about stuff outside of my control because it can have an effect on what I do control. When making a plan, I know success is never guaranteed, i.e., it's out of my control. I do, however, often have control of how I fail when or if I fail. I can take a path that should I fail it guarantees a certain effect and can preclude other, worse effects that could happen if I chose a different path. It's for this reason, unlike Destin, I'm unfortunately incredibly bitter and hold copious amounts of contempt for people in general. There are a great many "unavoidable accidents" that are actually avoidable and incredibly reckless.

[@Nefi424]

"I don't get anxious about stuff I can't deal with." Truly a wise man. I've been looking forward to the JWST launch for at least a decade and have always been nervous about it potentially failing. If minds like that of Dr. Mather are in charge, then there's very little to worry about after all. Can't wait!

[@MountainFisher]

"in 2011 after wasting over $4 billion their budget was cut for "billions of dollars over budget and plagued by poor management" so it's no wonder Mather doesn't want to take credit for being in charge since almost the beginning. Because the runaway budget diverted funding from other research, a 2010 Nature article described the JWST as "the telescope that ate astronomy". Well after Congress cut it the astronomical community led by a Congresswoman ran a publicity campaign for why taxpayers need to pay for their research toys and they've gone up another $6 billion since then. The reason you put real managers in charge and not a Nobel Laureate who doesn't understand that the money has to come from somewhere. SETI after losing taxpayer money acquired the funding they needed, but they stopped having so much waste.

I have to admit this video is one of the best videos I have watched discussing the Webb. Your simpler explanations above and beyond what Dr. Mather discussed are excellent.

Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable across a wide range of temperatures, from −269 to +400 °C. Kapton is used in, among other things, flexible printed circuits and space blankets, which are used on spacecraft, satellites, and various space instruments. Wikipedia

[@fubisroc9673]

@@mattsapero1896 Kapton Tape also works really well on circuit boards in the assembly phase. If you have a board that will travel through a wave-soldering process, yet there are portions you do NOT yet want exposed to solder (via holes, pads, etc that will be populated LATER), just slap a piece of Kapton Tape over it and peel it off when it comes out of the solder wave. Wide enough pieces are also good for on-the-spot, quick-and-dirty exhaust pipe repairs!!! :-)

Amazing interview Destin. What a brilliant and articulate man. I love how he he is quick to credit all the other scientists involved before taking any credit himself. That is truly a mindset that serves humanity. Besides the incredible science the most valuable thing I learned from Dr. Mather was his wisdom of “letting go”. Knowing that once you’ve done your best there’s no upside to worrying is a lesson we can all apply to our everyday lives. That was beautiful.

I had also assumed that JWST had an RTG onboard. Interesting that it uses so little power that an RTG is not needed. Great convo with Dr. Mather.

[@martialfantasy8772]

Interesting to see you here cub!

[@clapanse]

Other way around actually - it uses so much power that no current RTG would be sufficient. That's why it's using solar instead. If you wanted to run this with RTGs, you'd need something like a dozen of the ones used for Cassini to get enough power.

Haha what a pun. But for real, I think such an important telescope should get a re-naming after launch.

Many scientists and engineers who otherwise wouldn't get a legacy are the actual value-creation that is churned by such administrators.

[@man_on_wheelz]

What I love most about long-term science is that no matter who started the research, the ongoing teams of researchers will continue to look for the answers to questions originally asked long after the original team is dead and gone, coming up with newly improvised and higher tech ways to conjure up the answer almost making it certain we will have answers in due time.

@BrightForest Scholar's cradle is the way that lecturers hold their hands together while they speak/present.

You maintain clarity, your energy reserves last longer, and you may live a longer life with longevity also for various of your capacities. You just function better without too much stress and worry.
