    Atom Photo Quark
AI Thread Summary
Real photographs of atoms or quarks do not exist; instead, scientists use advanced imaging techniques like scanning tunneling microscopy to create visual representations. These images are not traditional photographs but rather detailed 3D representations that illustrate atomic structures. The discussion emphasizes the importance of using accurate scientific visuals for educational presentations. Participants suggest searching specifically for scanning tunneling microscope images to find suitable visuals. Ultimately, while true photographs of atoms are unattainable, there are high-quality representations available for academic use.

Homework Statement


I'm making a sort of physics presentation because I'm graduating high-school soon and my physics so far sucks and the low grades won't let me go in university... anyway I need to make it look more scientific, not like an illustrated book for kids. That's why I need some REAL photos of atoms, molecules (quarks would be awesome). But please, only real photos, not drawing, 3d animation etc etc.

The Attempt at a Solution


I've been Google-ing for a freaking day and I couldn't find anything. You are my last hope :)


P.S. I'm not really sure that such photos exist, but I had to ask

Well you've been googling all day for nothing. there are no photographs of atoms. There are 3D representations of atoms from scanning tunneling electron microscopes and the likes.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
