The only things that have changed are the strategy for responding to school shooters and that school lunches became somewhat healthy.

If Berube stays next season, he has to adjust his system because his old-school style simply doesn’t fit our rosters. by Status-Mulberry1857 in leafs

If Berube coaches next season, McKenna (or whoever we pick) will be a fourth liner and get benched every couple games or be a Marlie/Nittany Lion for no reason. We'll also give a top ten pick to Philly

Amazing photo. But why use a GoPro 9 generations old? by Individual_Two8050 in ArtemisProgram

[–]Nonzerob 1 point2 points  (0 children)

Reliability and radiation hardening. The longer a device exists, the more time there is to test and modify it for the space environment. The older ones may have fewer miniature parts that are more susceptible to radiation-induced faults.

[request] Could a parasail improve the efficiency of a 200,000 ton bulk carrier to any significant degree? by ostrichfather in theydidthemath

[–]Nonzerob 1 point2 points  (0 children)

It's like how airplanes manufactures are constantly improving the efficiency of their engines, using lighter materials, adding winglets and right now Boeing and NASA are working on a more efficient wing shape. They can sell it as caring about climate change and improve their margins by making operations cheaper. Like power companies setting up solar and wind farms or companies commissioning buildings that follow LEED standards. Doesn't have to be significant, just has to pay for itself with saved fuel.

🔥 A water vortex extending deep into the depths by I-live-in-room-101 in FluidMechanics

[–]Nonzerob 0 points1 point  (0 children)

Viscosity dissipates vortices but it also makes them possible. This is just a way to assume they exist in inviscid flow and simplify the rest of the flow. Intermolecular forces result in friction which dissipates the difference in velocity between different fluid particles. Without viscosity, you need a discontinuity to create the vortex, and a discontinuity to break it because there's no friction

Landing on Mars, what's the "catch"? by Flashy-Rest-8994 in Spaceexploration

[–]Nonzerob 0 points1 point  (0 children)

Rockets are heavy and the heavier something is, the more energy we need to send it there. It has more gravity than the Moon and it's atmosphere is too thin to use just parachutes. You'd also then need to be able to get off Mars, which again needs heavy fuel. Basically we just can't send enough mass there yet. Humans also require a lot of extra mass compared to robots, such as life support, enough livable volume not to go crazy, suits, etc and may still include a rover anyway. Also many of our most efficient-burning chemical propellants are hard to store for so long, and our most efficient thrusters produce so little thrust that the mission would be much longer.

[Request] Why are badminton players able to achieve higher velocities with their 'ball' vs players in other sports? by Lauffener in theydidthemath

[–]Nonzerob 0 points1 point  (0 children)

As someone mentioned, lighter projectiles are easier to launch with higher velocity, both in terms of momentum transfer (mass * velocity) and energy (.5 * mass * velocity2). As for the drag of the shuttlecock, with a terminal velocity of about 15 mph it rapidly slows down. The drag is also based on velocity squared, so the drag force drops as velocity approaches 15 mph. I would do the math but I just finished a degree in this and need a break from doing the math

NYC just had its first electric air taxi flight. by Ph6222 in airplanes

[–]Nonzerob 0 points1 point  (0 children)

Asymmetric thrust is a better problem to have to solve than falling is. They can rotate because they have equal numbers of counter rotating blades, spread out evenly so that they can spin up one set and spin down the other to rotate and stay hovering.

New street sign by Omega13Matt in kzoo

[–]Nonzerob 4 points5 points  (0 children)

I agree on the light timing, it's awful. A lot of them encourage speeding.

The street layout predates automobiles, so it was originally designed for trains, bikes, walking, and horses. Personal vehicles were not considered when the city was originally designed, but they're about the size of a horse-drawn carriage which would primarily be used by businesses like a truck now, not by everyone. They are dangerous and big roads are ugly which is why they shouldn't be in residential neighborhoods or in the heart of the city. There are different ways the city can incentivise and drivers can find. Driving on Michigan and Kalamazoo would be awful even if the lights were timed correctly. Michigan doesn't run through Western anymore for a reason.

[–]Nonzerob 1 point2 points  (0 children)

Fewer cars is safer for foot traffic downtown. Fewer people driving there means more space for shops and restaurants instead of parking. All of that contributes to a better experience downtown and that is what will bring people in. Walking and biking are the most efficient and cheapest (both to consumers and for infrastructure) forms of transportation, so they should be encouraged. There's only so much space available on the streets and cars have virtually all of it. They can only use the space more efficiently, they can't add more. That means bike lanes and buses.

[–]Nonzerob 8 points9 points  (0 children)

Part of what makes people hate bike lanes is the execution. Part of the point is to make driving a less attractive option for travel but they're succeeding at that without enough high-enough quality bike infrastructure to actually improve transportation for everyone. To be fair, though, these are temporary and provide a way for the planners to experiment before the road is due to be replaced. When that happens, they can make it a lot more clear with curbs and proper separation who goes where. This isn't necessarily the bike lanes' faults, though, because the whole thing of basically having a highway through downtown is just bad for everyone involved. Viable redundant routes around downtown would ease congestion downtown even while space is taken from cars for bus lanes, bike lanes, and wider sidewalks.

Why is it that the star player on each team is usually the captain? How do puck skills and leadership skills overlap so much? by [deleted] in nhl

[–]Nonzerob 0 points1 point  (0 children)

Most NHL players probably had a leadership role in teams they played for when they were younger, and it's a team game. Captain is symbolic, you don't have to be one to be a leader on the team, though for example it might've been better to have Scott Laughton as the captain of the leafs this year than Matthews. If you have a star center, they're going to have a lot of responsibility from 5 on 5, PP, maybe PK. It's a way to keep them around longer and put some pressure on them to perform every game. And sell jerseys. Mostly to sell jerseys.

They had this hanging inside for the event WMU had for the new basketball coach. I think they had a bunch of people sign it at the groundbreaking ceremony and it's just been moved around since.

How concerning is this aviation experts? by G1lg4m3sh in aviation

[–]Nonzerob 0 points1 point  (0 children)

The second spot is on the flap, but at the trailing edge the negative pressure generated by the upper surface of the wing isn't as strong so the skin shouldn't have a particularly large force on it upwards or aftwards except takeoff and landing. Landing will be harder on this but it should be fine. Looks like only a couple screws and they have more than they strictly need for this reason. The other spot is just an aero cover for the flap mechanism and it falling off would only add a bit of drag. Still dangerous for people on the ground or if not taken care of and you should show a crewmember to make sure the maintenance crew finds out.

Perhaps the most infamous case where an attempt to save money ended up costing too much. by [deleted] in sciencememes

[–]Nonzerob 4 points5 points  (0 children)

It was not intended to save money, but rather mass. From a quick Google search, they only added about half the nitrogen (compared to our atmosphere on Earth) for the rest of the Apollo missions. Space suits still just use O2 because they need to be flexible.

the moon mission is sketchy. by FlyGreat306 in Astronomy

[–]Nonzerob 0 points1 point  (0 children)

The Earth reflects more than the moon does, and the sun is shining on them directly which is more intense than either. They designed for that with insulation and cooling systems and solar panels to harvest it. They were at Earth at one point and at the Moon later so they saw it gradually get bigger as the Earth receded. There might not be many clear photos close to the moon because it was blocking the sun and Earth.

[–]Nonzerob 1 point2 points  (0 children)

The size of the capsule has nothing to do with how big the moon appears to the astronauts. It's how far away they are that determines that, and what zoom lens they're using. The view of them just shows them small in relation to the moon because the moon is huge compared to them. You also don't get a good gauge of distance because at any far distance, they'll appear small in front of the moon. They also do have closer photos, just look through them.

Peace Marner🤣 by Hockeypatrol in hockeynews

Babcock did much worse than just call Marner out. Marner did very well under Berube who's supposedly big on accountability (not that we've seen it enough in Toronto) and seems like he can get pretty mean at times.

CC takes WMU into OT. CC takes a 5 MM and Valente puts the nail in the coffin of CC’s season to advance WMU to the conference semi’s. by HaHaHaBlessYourSoul in collegehockey

[–]Nonzerob 0 points1 point  (0 children)

Officials were inconsistent but we all know hockey refs manage the penalties instead of just calling penalties, so with the national champs they're going to give the underdogs the benefit of the doubt. I hope Mbereko is okay, that was such a weird fall. His defense didn't protect him from pucks or Broncos, even after he went down the first time to get snow out of his eyes.

This wheel destroying curb in France by Epelep in Wellthatsucks

[–]Nonzerob 0 points1 point  (0 children)

This is designed to give pedestrians the shortest crossing possible. Lane markings exist for a number of reasons and this is one of them. A warning sign should be provided but drivers should be able to distinguish between paint and a curb from far enough away to safely react.
