atoms never touch each other because of electons

mercredi 30 avril 2014

Recenty I learned that there is not real touch. That atoms never touch each other because of electons. I have two question to this.



1) Why we feel the pain(I think is because of brain analysys but I am not sure)

2) Why if I press hard my hand,I will mark that?? Why this sign in my hand will be exists(I will get out the electrons from there?)



Thank you!!!
