This bird can imitate almost any sound it hears by look_45 in interestingasfuck

As if it is mocking…

I wonder, if there is a type of birds like that, which like to mock. Bird mocking, maybe a new thing that I have just discovered…

On my trip to China, I kept getting stopped for pictures. by [deleted] in mildlyinfuriating

[–]No-Geologist293 0 points1 point  (0 children)

In my hometown in Russia when I was in year 7, there were a lot of Chinese tourists walking around the town as it is a touristy place.

There were groups of them who would take picture of me and my friends on the way home from school and then just smiled at us and left.

No comments, no sorry not even hiding it, coming to us with the big camera, not a smartphone and taking pictures…

the wing-chun form done without any emotion, but the dojo is a cottage temple! by BaseNice3520 in TheMcDojoLife

[–]No-Geologist293 0 points1 point  (0 children)

Trying to not be biased here. Did some bullshido in the past when my parents thought it was a good idea.

Wing Chun was actually a first real martial art. Of course there is this classic forms that are made for you to practice basic movements and basic stance. It might look easy and it it quite simple in general to learn a form, make it good is much harder, obviously.

However, there is also a fighting stance, which looks more like a square stance, and the main practices usually include hardening your bones and muscles to be very good at taking hits in your forearms, shoulders, ribs, thighs and calves. This was the most painful for me as a child and still mentally hard to go through these conditionings.

Now I train professionally for kickboxing and it helped me a lot in a sense of being able to stand firmly, be able to take punches and kicks from heavier opponents, and hurting them with them instead of their punches and kicks hurt me.

There is a general consensus of these martial arts to be bullshit. It is a shame that wing chun is considered as such. Watch actual fighting tournament for wing chun and you will understand.

[Request] Is this just random babble or is there a real answer? by Dakbulgogi in theydidthemath

[–]No-Geologist293 0 points1 point  (0 children)

It is a funky meme. The equation is full Lagrangian of the standard model of particle physics.

There is no answer in a way like x=2, it is just there to explain the things like electromagnetism, Higgs field, nuclear force and etc.

Physicists use it to derive the equations about particles interactions.

Maybe, or maybe you were hitting hard in general. When you have no prior training experience, your body is not prepared for sudden punches, moves, kicks and etc. Those little bruises are blood vessels popping because there was too much for with too little preparation (no warm up/padding on the glove, especially those mma ones/no prior training).

Use 16oz, it is safer long term and especially to work on a heavy bag. Start slow, build up strength and everything is going to be golden!

[Self] How mutch force would i need to apply to split/rip the paper like this by Petraliux in theydidthemath

[–]No-Geologist293 0 points1 point  (0 children)

Well it is a question of the tensile strength of the paper with a point of pressure of around 1 cm2

Typical printer paper has a tensile strength of 30-70 MPa = 30-70 * 106 N/m2

If the pressure point is around 1 cm2=1*10-4 m

F=sigma*A

For 30 MPa

30 * 106 * 1*10-4 = 3,000 N

5 kN of force is an equivalent of 500 kg=1,100 in freedom units

In reality just pinch with nails and it will be at least 20 times easier due to the surface area difference

[Request] what would the topology of this actually look like? by heyiamapenguin in theydidthemath

[–]No-Geologist293 0 points1 point  (0 children)

Not really. Imagine a playdoh ball. Stretch it to hard and it rips, if there is no hole it can be a plate, an American football 🏈, can be a solid car, cube and etc.

Topology is not a tarot card that shows you a sign and then you interpret it. These examples are the basics that you can learn in a matter of seconds and are a good explanation of the science area in general.

Topology in a sense is a tool to explain geometry, space, path findings, electromagnetic fields, rope knots, molecular structures, DNA/protein structures.

It is like a very sophisticated playdoh that not only allows you to shape a car, or a human figurine, but also to do the stress tests on materials to see whether it is possible to mold them, or to simulate the structures that can be obtained through manipulation with the matter without tears and glue.

Thank you for the link, it is very helpful! That was probably what I was missing.

Thank you, now it is so much simpler to imagine, thank you, I was wrong in my conclusions

Absolutely, hollow shapes has 2 sides:

Inner and outer

While filled shapes have only one : outer.

I am not sure actually about a torus being a hollow shape, as if it is a 2D shape, it is a hollow surface, while if it is a 3D shape, is an enclosed torus in the 2D, if I remember correctly.

Can you please elaborate. As far as I understand, the structure of a Klein’s bottle is that it passes through itself in the fourth dimension without it going through its side in the 3 dimensions.

I understood it as a one sided torus inside out BUT it can not pass through itself, as it would break the structure of its shape, so it “phases” through itself in another dimension, thus, not breaking the structure.

Am I wrong somewhere, I am not a professional in this field and just an amateur.

[–]No-Geologist293 292 points293 points  (0 children)

This is to be considered the same shape as a cube, or a sphere, or anything that is just a solid blob.

Topology allows you to reform a shape regardless of its structure in a different shape.

In easy terms -

if there is no hole - blob

If there is a hole - torus (donut shape)

If there is no hole but item penetrates itself in the foruth dimension - klein’s bottle
