2022-06-16 09:00:56 WHY is the power of machines measured in horsepower?

Since the first steam engine was invented, it was necessary to determine its cost-effectiveness as a replacement for horses, and therefore how much money to pay for the machine. Some work was performed with a steam engine, then with horses, finding how many horses could do the same work - so we got power in horsepower.

The short term power of a horse is much more than 1 hp, the long term power of 1 hp can provide not every horse (it was beneficial to the buyer of the steam engine, so the horses were selected hardy enough).

Later on hp was abandoned as not related to other physical quantities directly, without coefficients, but for figurativeness and by inertia of thinking, technical devices, the power of which a person must directly feel (car, airplane, ship) left for use the expression of capacity in horsepower.

2022-06-15 09:01:56 WHY and how did Theodore Roosevelt address the voters for an hour and a half with a bullet in his chest?

When Theodore Roosevelt was running for president in 1912, he was shot during one of his meetings with voters. The bullet hit him in the chest, penetrating his eyeglass case and the thick 50-page manuscript of the speech he wanted to give.

But Roosevelt stayed in place - he drew the audience's attention to the fact that he had just been shot and then spoke for an hour and a half. His hunting experience helped him to realize that the wound was not life-threatening - since he wasn't coughing up blood, the bullet hadn't pierced a lung.

It was later confirmed that the bullet had entered his chest at 76 mm, but it was even riskier to remove it than to leave it as it was, and Roosevelt wore it all his life.

What you are saying does make sense until you realize that your premise is based on a bit of bad information

2022-06-14 09:01:05 WHY does a human only breathe through one nostril?

Roughly every 4 hours, there is a change in the "lead" nostril.

This phenomenon has a name: the nasal cycle. Namely, the two parts of the nose are able to change the resistance of the mucosa in response to the air flow passing through them. That's possible due to the special structure of the blood vessels in the nose. The cavernous body swells, blocking the passage of air, or, conversely, shrinks in size.
