Engineering is a branch of Science. Specifically, Engineering is applied science. For example, scientists discovered that microwaves existed. Engineers made them heat up your food. How did we make safer and better microwaves appliances? Engineers applied the scientific method and iterated on the design and performed tests.

To say engineering is separate from the science is incorrect.

It was actually a scientist who made the first microwave.

They were doing experiments with hamsters with cryogenics, and warming up the frozen hamsters with hot paddles. It didn't work that well, and the scientist felt bad for the hamsters.

So, he built the first microwave to warm the hamsters more evenly and 'humanely'.

That's right. The first thing cooked in a microwave was literally a hamster.

EDIT:

First Desktop microwave that matches what we consider a microwave today, I should have said. My apologies.

The sources on wikipedia say it was Percy Spencer, an American self-taught engineer. He noticed a Mr. Goodbar candy bar he had in his pocket started to melt from microwaves from an active radar set he was working on. The first food deliberately cooked was popcorn, and the second was an egg, which exploded.

If you have a link to the hamster experiment I would love to read more. I might dive into a microwave research hole today! lol
