What is the difference between atoms, particles and matter?

So I'm in year 10 (9th grade for the Americans) and I just had a question about physics. What is the difference between atoms, particles and matter? Are they all...

Mass renormalization with counterterm for scalar field theory

Sidney coleman in his lecture 253a of QFT stated that " one-meson-to-one-meson S-matrix element, we should find it equal to 1" i.e $$langle p'|S|prangle = (2pi)^32E_pdelta^{(3)}(vec{p}'-vec{p})tag{1}$$ for the scalar...

Pressure in a 2D Ideal Gas simulation

I am currently creating a 2D ideal gas simulator whereby the user can determine three of the four variables (P, V, n, T) and the gas would adjust accordingly. I...

What really allows airplanes to fly?

What aerodynamic effects actually contribute to producing the lift on an airplane? I know there's a common belief that lift comes from the Bernoulli effect, where air moving over the...

Is the statement "The deactivation sensor sends a signal to disarm the bomb" frame-independent in the train-tunnel paradox?

The following problem is taken from Exercise 1.7 in David Morin's "Special Relativity: For the Enthusiastic Beginner":A train and a tunnel both have proper length L. The train moves toward...

Would there be any changes in polarisation for light that is diffracted by diffraction gratings?

My understanding is that s and p polarisation of light will have a different angle when diffracted by diffraction gratings. In wikipedia it says that "According to the Huygens–Fresnel principle,...

What are the cosmological ramifications if we probabilise and continuify the order of differentiation in $F=frac{d(mv)}{dt}$?

Newton's second law of motion states that $F=frac{d(mv)}{dt}$. This is a first-order differential equation, in which the order of differentiation of momentum is 1. So we can write it $F=frac{d^k(mv)}{dt^k}$...

Can we make a rigid ball rotate steadily by shaking a curved surface on which it stands?

I would like to know how to analyze the dynamics of a ball on a curved surface (lower part of a sphere), which can move in the xy plane. To...

Diffraction pattern vs Interference pattern

I am not confused with difference between Young's double slit experiment and diffraction. In Young's double slit experiment, the interference pattern is bright fringes separated evenly with separation given by...
