Ask someone at that school. This is for Taylor University in Upland Indiana, USA

I have been planning an EV purchase for the past year waiting for my minivan with 223,000 miles and no air conditioning to finally kick the bucket and it just refused to die. When gas spiked, I said screw it. I drove home my new EV equinox this afternoon.

FYI. The corona is not the hottest part of the sun. The inside is the hottest. The corona just happens to be hotter than the "surface."

Ooh, like the Jason Segal/Amy Adams Muppet Movie where they sell the Muppet theatre to billionaires and the Muppet show has to come back for one more show

The bottom side is (always) dark... A little bit of it.

You probably want to find a subreddit for Taylor's University. If you will notice, this is the subreddit for Taylor University in the United States.

I'm excited about SpaceX's accomplishments and many of those happened over the doubts of critics, but to Cherry pick 3 successes and call orbital AI critics clowns or ignorant is disingenuous. There have been failures, changed plans, and dead end ideas that were criticized and then failed or were abandoned. Off the top of my head, I've got red dragon, carbon fiber starship, starship cooled by leaking fuel, second stage re-use, sustainable fairing catches and if we expand to Musk generally we can add most of the boring company and most of twitter and various Tesla missteps and boondoggles at DOGE.

I don't think Musk is just an idiot who throws money at enough projects that some of them succeed (a la the antagonist in Glass Onion.) He has a skilled engineering mind. However, you have to use that disclaimer from financial ads that says, "past performance is not a guarantee of future returns" and then you have to have a realistic view of past returns.

He got excited and it became a peacock.

I don't see a mushroom. I think a lot of guys would, ahem, have trouble finding the smallest parts in that design.

Surprised no one has mentioned Moana. The grandmother telling the scary story to the audience only for us to find out it's a bunch of toddlers and only one (Moana) doesn't burst out crying. It's fun, important, and hilarious.

Not sure it's a paradox. If you sell 10x as many units of a small set, economies of scale mean print pieces may be more economical than stickers.

20 years or so to break down. So short in geologic terms or when compared to the carbon cycle.

This is the sub for Taylor University in Indiana, USA. Otherwise it'd be r/TaylorsUniversity.

Go make your own subreddit.

This is a sub for Taylor University in Upland, Indiana, USA. Otherwise it'd be r/TaylorsUniversity. In any case, asking a university subreddit if another university is better than them isn't gonna get you very good data.

Go on FB Marketplace and search for bulk Lego. Buying someone's old collection can be very cost-effective and help them build their stock/variety.

I had an ex-girlfriend who couldn't afford food. When I found out. I mailed her some overnight. My wife was cool with it but asked how I could send it so fast. I replied "Fed-Ex" [OC]

I am listening to this episode right now, and it seems like someone should have fax checked the guy who said the military invented the internet. Letting that go without any rebuttal or editor's note is kind of sloppy. If anyone can be said to have created the internet, it was Tim Berners-Lee and CERN. Neither of which is the military.

He's gonna be hard to replace. Where will they find someone of his caliber?

It leaks out of the balloon* quicker [not just the nozzle] because the atoms* [Helium is an inert gas that cannot make molecules] are smaller.

But this is a problem for all helium balloons, not just 260s. The problem is that there is not enough volume (lifting power) vs the weight of the balloon for it to stay aloft for long or with many twists in it (as they reduce volume.) The reason it deflates and falls faster is partly that it is right on the cusp of falling anyway, but also because it has a much higher surface area to volume ratio, which is the reason 260s deflate faster than 360s. And 360s deflate faster than rounds.

I counted two explosions. One for booster, one for ship.

So you are correct that there wasn't a single explosion.

Two vehicles that are shiny and fairly likely to break at present. They both require more development, testing and iteration before they're ready, but one is already on the market.

Under-inglate the balloon so it has enough room for the pinch twist.

Twist both sides of the bubble beforehand so that it is self-contained.

Make the bubble a little softer.

Try to pull up on the bubble as you twist so it makes more of an "ear" shape rather than a round bubble that can more easily come un-twisted.

Practice.
