Torque - what is it, and how do we find it?

 For objects that can rotate, it turns out that applying a force to it doesn't necessarily mean the object will rotate. It also depends on where the force is applied, and at what angle it is applied. This combination of force, distance and angle is called torque. 

This video introduces how to find the magnitude of torque, Frsin(beta), and provides numerous examples of how to find the torque due to various forces. Check it out, and see if it makes any sense. 

What cosmic radiation can do to electronics

 An interesting effect that does happen from time to time on earth, and frequently in satellite electronics, is cosmic radiation coming through and causing damage to electronics. This Veritasium video gives a number of real examples, as well as the science behind it. Some of you may be interested in this!
