"DO THINGS TOUCH", 

Do atoms touch, do molecules touch each other, can we touch someone in the real world or not.??? These types of questions are quite a lot on the internet and in physics or chemistry forms. This question is related to the topic of  "NON-CONTACT ATOMIC FORCE MICROSCOPY".

So, do we really touch anything? So how can we define that we are touching something? zy

Well, I think it's hard to say that the things touch each other because whenever we came to contact with anything, the electrons present in the molecule of our body and other body attract each other but after a point where the force of attraction becomes the force of repulsion ("Equilibrium")  at that point we can say that we are touching something. 

 So touching is just the balancing out of these two forces and we can't move the atom closer after this point. Scientifically we can describe the true contact between two particles as the point at which the space occupied by the electron could have no "Planks length" between it and the space occupied by the other electron. But Quantum mechanically this not possible because by doing this we are overlapping the electron and there is no space between them which also don't satisfy the "Pauli exclusion principle " at all.  

So the question arises that what we feel when we touch anything. Eventually, we interact, the particle in ourselves are interacted with each other by a force-carrying particle called "Bosons". So everything that you do like kissing your girlfriend, hugging someone, sitting on a chair, etc is nothing but electron-electron repulsive force. But if you really want to touch someone you need to radioactive. because radioactive elements interact directly to the nucleus of atoms with radiation. Only this way we are able to touch someone atomically.

 well, there is another way to get chemically, reactionally close to a person. Luckily, there is a thing called birth, when you are growing inside your mother, your father's and mother's DNA are working together in a chemical way to create you. Because in this process they are sharing electrons it seems at least more like a touch. So you can that your parents are the only person that you have come the closest ever to actually touching. And that's touching so you never touch anyone ever except the cells of your parents do in the birth process of yours.
