Be aware that feeling sleepy after lunch is related to digestion.
The main reason why you get sleepy after lunch is because food that you eat for lunch diverts your blood away from your brain to help with the digestion process. Your body also releases a bit of melatonin after lunch related to a drop in core temperature that occurs around 2 to 3pm. Melatonin is a hormone that helps you fall asleep at night.

How to Become an Astronomer ?
Astronomy is the study of the stars, planets, and galaxies that make up our universe. It can be a challenging and rewarding career that could lead to amazing discoveries about the way space works. If you have a passion for the night sky, you can translate that into a career as an astronomer by getting good grades in physics and mathematics. You should then develop the skills and experience necessary to land a good professional position as an astronomer at an observatory or even a space agency like NASA

What is a ferrofluid?
A ferrofluid is a liquid which becomes highly magnetized in the presence of a magnetic field. The distinctive ‘spikey’ shape of a magnetized ferrofluid is caused by the need to find the most stable shape in order to minimize the total energy of the system, an effect known as the normal-field instability. The fluid is more easily magnetized than the surrounding air, so is drawn out along the magnetic field lines, resulting in the formation of peaks and troughs. However, the extension of the ferrofluid is resisted by gravity and surface tension. Because ferrofluids are very easily magnetized (they have an incredibly high magnetic susceptibility), the peaks can be produced using a small bar magnet.
