Recently, our Science and Innovation class had a unique opportunity to get acquainted with Tom Vales. An amazing professor who definitely knows how to introduce the physics to the class and make it entertaining at the same time. The main topic which Tom covered were types of engines and machines.The first experiment which the Professor introduced was the experiment with the stirling engine. The machine works with the help of heat. Professor Vales put the engine on top of a special cup filled with water. The heat which rose in the cup was trapped and under the piston created heat and as a result – a working machine. Tom added that the machine is 200 years old and is still widely used nowadays.

Next Professor Vales showed us the Peltier Junction. The machine generates an electric current and uses a thermoelectric effect to create very cold temperatures.

After that Tom introduced the Mendocino motor. It has 4 solar cell magnets which generate the power which the motor uses to levitate. This motor also uses its own magnetic field to float. The magnetic which the motor has converts light into electricity.

Professor Vales broadened our minds with the topic of electricity and how engines and motors use it. The office which the Professor has is amazing. The machines and gadgets there truly show the amazing power of Science and how electricity can be used to assist a person in daily life. I loved his method of explaining and he has a great personality as well. It was an amazing experience. Thanks Tom!
