5 Special facts about physics!

5 Special facts about physics!

1.I’m already at my ideal weight… on the moon.

Weight (force of gravity) decreases as you move away from the earth. This is because, although we don’t tend to think about it much during our lives on Earth, weight is not actually an objective measurement of how much matter a thing contains—that’s what we have mass for. Weight is a measurement of how much gravity something experiences, which is a function of what other bodies are surrounding said object, and how they themselves respond to gravity.

2. Take that, astronauts!

Some roller coasters have been known to include g-forces of around 4 to 6 g. Astronauts normally experience a maximum g-force of around 3gs during a rocket launch. Have you ever been to a theme park? Congratulations, according to my very hazy understanding of the transitive property of equality, you are officially an astronaut. Congratulations, Doctor. Stay humble.

3. Sweet equilibrium!

The Sun and the planets are staying approximately the same distance apart and have been in roughly the same places for several billion years. The planets currently lie in a perfect balance that results in each planet moving fast enough to not be pulled closer to the Sun, but not too fast that it moves away from the Sun and launches of the Solar System

4. If Saturn went for a swim…

Saturn would float if you put it in water. Technically, this is true since Saturn, which is composed mostly of gas, is much less dense than water. However, finding a pool of water big enough may be a challenge… And, of course, the planet itself may not be the best swimmer. Most physicists agree that Saturn would fall apart pretty quickly if ever plopped it into this yet-to-be-discovered colossal pool.

5. I think I get it, but I’m not sure.

The Uncertainty Principle, or the Heisenberg’s Uncertainty Principle, is one of the most famous and misunderstood ideas in physics. It states that the position and momentum of a particle cannot be simultaneously measured with high precision. In layman’s terms, this means that there is a fuzziness in nature, a fundamental limit to what we can know about the behavior of particles and, therefore, nature. This radical principle caused many physicists to change their goal. Many physicists acknowledge that the goal of modern physics is no longer to understand the nature of the universe entirely, but rather to understand it within the limits of the Uncertainty Principle.
