In condensed matter physics, a time crystal is a quantum system of particles whose lowest-energy state is one in which the particles are in repetitive motion. The system cannot lose energy to the environment and come to rest because it is already in its quantum ground state. Because of this, the motion of the particles does not really represent kinetic energy like other motion; it has "motion without energy".

Theorized form of matter that could exist in the cores of neutron stars.

Essentially matter compressed beyond a critical point where protons and neutrons break down and dissociate into quarks.

If this quark matter contains strange quarks, then it is called strange matter.

Well first of all, fuck you smartass.

But also yes, you're right

I wouldn't even try to defend OP, but I once heard someone say that if you have more than four apples, then it is also definitely true that you have four apples.

[-] lolcatnip@reddthat.com 18 points 8 months ago

That's true in a very literal sense, but there's a whole branch of linguistics called pragmatics that's concerned with things like why it's usually safe to conclude that when someone says they have four apples, they mean that have only four apples. When there's any ambiguity I talk like a mathematician and use phrases like "at least four apples" or "exactly four apples".

[-] pearsaltchocolatebar@discuss.online 14 points 8 months ago

It's technically correct, like saying at least 4 people died from covid.

[-] Lightdm@feddit.de 17 points 8 months ago

More specifically: "4 people died from covid" is also true

As a teacher, this type of response is a great jumping off point for the discussion of curriculum vs truth, what is the extent of reality vs what is going to be on the assignment / exam etc.

It's also a great way to stick it to the know-it-all who is trying to undermine my credibility, and has the added bonus of perking up the rest of the class.

[-] Rodeo@lemmy.ca 12 points 8 months ago* (last edited 8 months ago)

If you can actually have a reasoned discussion about it, instead of simply getting angry at being questioned, then you are better than 90% of teachers.

In my experience most teachers don't like being questioned, which of course is directly antithetical to their supposed vocation.

Taco Tuesday leads to Plasma Wednesday.

[-] PhlubbaDubba@lemm.ee 52 points 8 months ago

My earth science teacher denied plasmas are a thing when I mentioned it

This was 8th grade

I Immediately lost all respect for her and if present day me were around for it I'd have taken her idiocy to the union rep to recommend she prove she actually has the education she claims to have had.

[-] illectrility@sh.itjust.works 38 points 8 months ago

There is a point in everyone's education where they realize that their teachers are actually just adults, who are just old children, that went to school a couple years longer than you.

Mad respect to teachers though. I specifically remember my computer science teacher to be the coolest and most knowledgeable guy ever.

[-] Retrograde@lemmy.world 9 points 8 months ago* (last edited 8 months ago)

There are a lot of great, brilliant, committed and dedicated teachers.. but also, unfortunately, some pretty bad ones too

My 6th grade science teacher tried to explain that Chernobyl was foretold in the book of revelations.

This was a US public school. In the 90s. In a blue state.

Middle school teachers in Texas only require a generalist certification, a Bachelor's Degree, and completion of a teacher training program to teach core subjects. That cert (which also exists for elementary school teachers) requires only a basic understanding of each core subject area. There are certifications specific to each core subject (I have Math 4th-8th, also Math 8th-12th, along with a Master's in math), but there is no guarantee you're going to get a teacher certified in their field. As such, you get teachers who don't understand their subjects at a very deep level or how what they teach connects vertically to their student's prior education in that subject and what they'll learn in future grades.

It is a big reason why students to come to my high school classes hating math, I think, because it was confusing to them being taught by teachers who only had a moderate understanding themselves and probably taught them lots of memorization tricks and mnemonic devices instead of helping them understand their origins and why they work.

You're probably the kind of person who complains that they don't teach complex numbers when first introducing square roots in school.

[-] illectrility@sh.itjust.works 41 points 8 months ago

Not really no. It's a meme. Although, now that you mention it …

“This is a triangle. It has three sides and three vertices.” [proceeds to give a collegiate trig course to the dismay of kindergarten students]

[-] PM_ME_VINTAGE_30S@lemmy.sdf.org 11 points 8 months ago

I pretty distinctly remember being introduced to square roots at the same or nearly the same time as complex numbers. Obviously we didn't do the whole Complex Numbers Extended Cinematic Universe, but I think my class did learn to solve quadratics with complex roots in middle school.

I mean I did go to Catholic middle school, but I don't think the math education was that weird.

Preferably you want to note it's existence on the way past. But leave it there.

It's one of the maths areas that is complex enough to wow them, while still simple enough for some to research on their own.

You could also wait for the first smart Alec to ask about negative square roots, blow their brain with a quick simplified answer, and move on.

Yep, this was me, but it was pointing out the particle wave duality of light. Needless to say I was mocked by the teacher and students.

[-] gandalf_der_12te@feddit.de 19 points 8 months ago

I disagree. In physics, you choose the simplest model that works for a particular purpose. If it is enough to assume that there are three phases, then that's the simplest model that works, and therefore the "correct" one to use. A model that has four phases is, then, bloated.

[-] MotoAsh@lemmy.world 15 points 8 months ago

Did the same thing to a science teacher when they said, "light only travels in a straight line" thing. It DOES only travel in straight lines, but refraction is a thing, and geodesics are never perfectly straight.

[-] JPAKx4@lemmy.blahaj.zone 22 points 8 months ago

Bonus, it only travels through a straight line through curved space, so to an outside observer the light did curve.

My high school taught the quantum mechanical model of the atom instead of whatever simplified model most high schools teach.

I found out this was a huge advantage taking university chemistry because I was like "cool this is all review I'm gonna ace this," but everyone else in the class was like "what the fuck is going on this isn't what they taught us!"

I may have messed up the curve that quarter...
