online lecture by Gerhard Heywang on April 5th, 2022 at 3 p.m

Moderator: Eberhard Ehlers

Everyone has eaten an egg at some point ? you have probably indulged in the pleasure without thinking about the interesting questions and worth-knowing answers hidden behind eggs.

The experimental lecture deals with aspects relating to the egg and answers questions such as: Why do you need a lot of water in the egg cooker for a few eggs and little water for a lot of eggs? Why are eggs deterred? How round does the egg come out of the chicken? Which chickens lay white and which brown eggs? What is the dye in brown eggs made of? How can you tell if an egg is boiled or raw? How long does it take a chicken to produce 8g of protein for the egg? How long does it take for the shell to form? Are chickens stupid or smart? And much more.

The tongue - a jack of all trades

online lecture by Gerhard Heywang on October 11, 2022 at 3 p.m

Wolfgang Gerhartz

The tongue is a very versatile organ. It helps with speaking, swallowing, chewing and many other oral activities. The tongue consists of 9 different muscles, each of which can only contract, but you can still stick out the tongue. How does it work? And how does that work when a chameleon can catapult its tongue out as far as its own body length? How does a gummy bear taste if you just put it on your tongue? Does salt always taste salty and isn't hot chili actually a bodily harm? Who can roll the tongue? And what happens with the rolling R? Overall, it's about physics, biology and chemistry in the oral cavity. The listeners are asked to have a gummy bear and a grain of salt ready.
