Another way to view it is that college classes are filled with your future colleagues, and should be treated similar to a workplace. Students should generally dress similarly to how they expect to dress in their future workplaces. Whether that excludes a tank top is a matter of discretion, but clearly the proffesor did not find it to be professional. There's no hard and fast rule, but I am surprised by the indignant tone in the comments here. Lectures are the domain of the professor and its not outlandish for them to set expectations about what they consider acceptable conduct for their lectures.
The issue is that it's a waste of resources. A dam is harnessing energy from the rainfall over hundreds to thousands of square miles of land area. So the resources required to build it, even though large, are very efficiently used over decades of use.
A tiny system uses orders of magnitude less materials but harvests many orders of magnitude less power. A tiny system probably isn't going to ever generate more energy than it took to manufacture.
Systems like this are at best a novelty. We need to all be wary of greenwashed scams, and this is one of them.
Hegseth has got to stop leaking his chats.
It's actually a banana for scale, but photoshopped to look like a B17.
Not real.
And in this climate, I find this flavor of satire more exhausting than funny.
The other benefit I can think of is keeping the fissile materials always sub critical. You don't have to worry about a meltdown if the reaction is not self-sustaining. It's an odd marrying of technologies, but I think people are being too dismissive.
Although, I wonder if the true purpose of such a device would be high output breeding of fuel for weapons use.
The stuff that is heavier than water ends up in the river delta, everything else dilutes into the ocean. Once it's in the ocean, there's not much humans can do about it. Promoting populations of sea grass and filter feeders like mussels can at least capture pollution in a form that settles to the seabed and improves water quality.
There will be pockets of pollution that persist for a long time, and floodwaters could stir some of that back up, but the above poster is correct. Cleaning up a river can be as simple as stopping the sources of the pollution. A dirty river is dirty because stuff keeps getting added to it. Of course stopping sources of pollution is way easier said than done.
They already thought of that. The department of education has already been dismantled. If there are no school nights there's no problem, right?
Detroit essentially exists in both the US and Canada. The Detroit automakers have factories on both sides of the border but within the same region. So a Canada tariff war will always disadvantage them.
That said, the f-150, Ford's most popular vehicle by far, has only 45% US/Canadian origin parts.
On the ranking of vehicle models by how much of the vehicles construction is domestic, Ford's highest entry is #35 with the mustang, the F-150 comes in at #58. The "American auto makers" are all produced in America less than Tesla, Honda, VW, and Toyota. Tariffs can't save American auto makers, because they are less american than their German, and Japanese competitors. Tesla is the only "true American" brand, but they aren't viable as a major auto maker for a variety of reasons.
Is the sales tax in your area 7.5% by any chance?
$16 x (100/107.5)= $14.88
I don't see any gloves priced at 14.88 on their website at a quick check. I wonder if the store is trying to set a price that tallies to an even dollar amount and doesn't know the connotation. I only recently learned about those numbers being associated so I would like to believe a benign explanation. Maybe you could ask to talk to a store manager next time you see it an make sure they know to avoid that price point.
Maybe the non-morons don't make a point of telling you they have an MBA.
The article doesn't spell out the broader context for laymen like me. Can anyone clarify some points. Are these images taken from biopsies of tissues that are already suspected of being cancerous? Is this work translatable to preventative screening in a way that I'm unfamiliar with, or is it limited to processing biopsies?
For automated tools like this, what sort of protocols are established to prevent doctors from being biased by the tool output? Does the person running the test provide their findings before they see the output of software detection?

I don't like this system for two reasons.
The first being that bookshelves should have a restraint system that attaches to the walls. You could probably improvise something, but the video lacks that element.
The second is that the alternating brick pattern is weak for an open faced box. That puts a significant portion of the weight of higher courses on the middle of the span of lower courses. You can see some of the lower levels bowing signicantly. Since the back is rigid, but the front can flex, that will increase the tendency to tilt into the room and makes the tipping hazard worse. Add in an old floor that is concave and you have a significant hazard.
I like the concept, but this needs some changes before it is safe.
Edit: I'll suggest potential improvements rather than just naysaying. You could make two different width boxes. A full width and something like .8 width. You would stack the boxes alternating full width with partial width. The full width box would need 4 alignment pins and 4 slots. The boxes would stack in line vertically, but due to the alternating widths would still lock adjacent columns together. The important thing is that the vertical walls would be close together rather than landing in the middle of the spans.
Then I would add a cap board that can be bolted into the top boxes and would be used to attach a L bracket to a wall stud. Yes, this decreases portability, but not crushing children is more important than convenience.
Do the terms of their employment change when they get rehired?
Have you ever seen examples of how the features that ai picks out to identify objects isn't really the same as what we pick out? So you can generate images that look unrecognizeable to people but have clearly identifiable features to ai. It would be interesting to see someone play around with that concept for interesting ways to fool tesla's ai. Like could you make a banner that looks like a barricade to people, but the cars think looks like open road?
This isn't a great example for this concept, but it is a great video. https://youtu.be/FMRi6pNAoag?t=5m58s
Right, those were the failures that really matter, and Rober included the looney tunes wall to get people sharing and talking about it. A scene painted on wall is a contrived edge case, but pedestrians/obstacles in weather involving precipitation is common.
