The generation of random numbers has many uses (mostly in statistics, for random sampling, and simulation). Before modern computing, researchers requiring random numbers would either generate them through various means (dice, cards, roulette wheels, etc.) or use existing random number tables.
Yawning, swallowing or chewing helps open the small canal (Eustachian tube) which connects your middle ear in the inner side of the ear drum, and equalizes the pressure with the outer side and causes the sensation of ears popping when swallowing.
When the pressure equalizes (the pop), whatâs basically happening is that air is being released through the middle ear to the throat via Eustachian tubes. Our ears, nose and throats are all hooked up, which is why something like yawning or chewing gum can help alleviate the situation.
