Given the 2nd Law of Thermodynamics, our universe ends by the big freeze. Thus, how likely is the multiverse just all possibilities (thereby parallel universes) since the making of our universe? Why? How?
Hi I am trying to model a cutting problem with a blade and comparing the results with and without ultrasonic vibration. From experimental results in our group, the use of ultrasound can...
