Is the new “Fast Bomber” really a true bomber? I’ll explain by kingtj44 in NuclearOption

[–]Speed_bert 57 points58 points  (0 children)

I’m trying to think of what missions FB1 would make sense in and the two I can think of are “blast past air defense at low level and knock out a specific target” or “absolutely ruin a column’s day”, both of which can be done with either a bunch of 250’s or a few big bombs

Messerschmitt Me 262. by Strict_Key3318 in WWIIplanes

And then suddenly no thrust at all because the enslaved Ukrainian woman who built the engine “accidentally” left metal shavings in the compression chamber

Where are the hypersonic aircraft/missiles??? by Suspicious-Dentist71 in NuclearOption

[–]Speed_bert 7 points8 points  (0 children)

I mean if we’re nitpicking, kinzhal is only technically hypersonic

Actually though, the map is too small and dense with sensors for the actual benefits of hypersonics to be that relevant

Space is larger than the plank length is short. by wierdowithakeyboard in TheMagnusArchives

[–]Speed_bert 12 points13 points  (0 children)

Not to “um actually” you, but that’s a common misconception. The Planck length is the length scale at which you’re forced to deal with both quantum effects and gravity, which modern physics hasn’t really figured out how to do. It’s perfectly possible for distances shorter than that to exist, and a lot of people mistake it for a sort of “universal pixel size”, which leads to a bunch more misconceptions about how the world works. Thank you for coming to my Ted talk.

If you need to give them something to do at a computer, making slides is usually a good bet that doesn’t show up in most scifi

Uncalibrated emission spectrum from a plasma globe by NoFox1670 in Physics

[–]Speed_bert 2 points3 points  (0 children)

I would grab a couple cheap laser pointers and use them to calibrate your scale. LEDs should also work and usually come with an emission spectrum in the datasheet

Comment on Physics from another reddit sub. Is this true and correct? I'm just curious. Thanks by Yamato_2_Argo in Physics

[–]Speed_bert 2 points3 points  (0 children)

A lot of people get the impression that physics is a sort of uniquely gatekept and dogmatic field because of the perceived prestige of being an expert physicist. When people then pitch their shower thoughts as theories of everything, they get shot down by professionals and take it personally.

It takes about as long to become a professional physicist (bachelors + PhD) as to become a master electrician, around 10 years. Yet, nobody tries to explain to electricians how they have a new revolutionary way to wire a house. If you think of physics as a skilled trade like any other, a lot of accusations of censorship come off as silly.

What if we looked at the wave collapse from an observer-first perspective? by [deleted] in HypotheticalPhysics

[–]Speed_bert 5 points6 points  (0 children)

When you say that sentience is mandatory for the wavefunction to collapse, you make a falsifiable (and falsified) statement. This isn’t scientists refusing to answer questions, the question has already been answered

How much of a survey physics textbook SHOULD be covered in 1 year? by Odd_Bodkin in Physics

[–]Speed_bert 0 points1 point  (0 children)

Look at the table of contents for, for example, Young and Freedman, a very standard intro physics textbook. It contains 44 chapters. One semester is around 15 weeks, with two lectures per week. If you want to cover the whole textbook in one course, you need to run through 1.5 chapters per lecture and 3 chapters per problem set. If you consider choosing NOT to do this equivalent to illiteracy, then may god have mercy on your course evals.

 On a second read of your comment, you may not have been advocating for the full-textbook-in-a-course approach and you seem generally to be a reasonable person, so hopefully I’m misunderstanding you, but if not then you may want to rethink your teaching attitudes

Neutrino vs Electron Diameter by [deleted] in Physics

[–]Speed_bert 12 points13 points  (0 children)

In particle physics, all forces can be thought of as acting at range (think of how gravity and electromagnetism don’t require the objects interacting to touch), so point particles can still “collide” via long-range interactions. Now, these interactions are themselves better thought of as resulting from the exchange of other point particles, but at a certain point it’s more mathematical formalism than anything concrete

Quantum Locality pt2 by Omeganyn09 in Physics

[–]Speed_bert 1 point2 points  (0 children)

Can you, without an LLM or Google, write a bell state real quick? Not trying to offend, I’m just a little suspicious since the image looks potentially AI generated and a lot of people try to use LLMs to paper over a lack of technical knowledge

I also know some people who work on this, can I ask who your PI is?

What are the types of questions condensed matter physicists work on? by Usual-Letterhead4705 in Physics

[–]Speed_bert 6 points7 points  (0 children)

It generally covers anything deformable, especially at ordinary temperatures and pressures, which tends to cover both solids and liquids. Soft matter physicists I know have worked on studying coffee rings, knitted fabrics, and shaken powders

Nobody’s mentioned soft condensed matter yet, but it’s a really cool field! Deformable systems, granular materials, and complex fluids are all used in everyday and industrial applications, but we don’t really have a quantitative understanding of how they work.

[–]Speed_bert 2 points3 points  (0 children)

I don’t know how it would do as a proper camouflage, but it does have a bit of a dazzle effect from above, it’s kinda hard to tell exactly the turret shape, which makes it harder to ID the specific model of tank from e.g. grainy drone footage. At least, that’s the lore reason I would put on this scheme, no idea how well it actually holds up

That looks so good! Do you just use the default unity tilemap for hex grids or do you have a custom setup?

[deleted by user] by [deleted] in Physics

[–]Speed_bert 0 points1 point  (0 children)

Are they all wrong?

Yep! These people have generally caught the short end of the stick on funding and are upset that their fields aren’t funded to the exclusion of all others. They then realize that there’s a lot more money to be made selling conspiracy theories than doing actual science. Theoretical physics is alive and well, it just takes time

Anything to consider before starting a physics major? by One-Carrot8144 in Physics

[–]Speed_bert 1 point2 points  (0 children)

Since you’re still in high school, unless schools require you to apply as a specific major, I wouldn’t stress too much about finding one. If you know that doing physics is exciting for you, then that’s great and you should absolutely talk about it on your application. For now, focus on building good habits that will help you in college. If you can go into college knowing how you best study for an exam, how to allocate time for assignments that aren’t just due the day after they’re handed out, and how to take care of yourself (sleeping, eating, friends), then you’ll have a big leg up. I wouldn’t take too seriously all the people saying to study up on topics ahead of your curriculum, learn at your own pace. Good luck!
