Don’t Quit gave an intense tone to express the seriousness of being motivated; to strive for success after graduation, before graduation, or for that upcoming exam. Though, it hit me hard when they mention phones; its completely true. I have a hard time getting off my phone since it became my main communication/education tool, especially in quarantine; I manage an organization’s social media, speaking to teachers and students, handing in work, etc. It became so involved with my life that I got pulled into YouTube, and the app store when I’m taking breaks and pulls me to put of other tasks. I realized this before, but this video turned it into a pressing issue for long term goals.
Its pretty tough. The guy goes explaining if you want something so bad, sooner, you had to make sacrifices; but that sacrifice could be anything: your hobbies, sleep, food, maybe even friends or special plans (but TV shows I get since they don’t disappear for a few decades). So, besides teaching how to work to be successful; it made me realize that I have to be sure what I’m throwing myself into, as currently, I don’t have a goal that I want so much to throw away everything.
I assume this post is more for people who watch and get slightly discouraged because they didn’t try hard enough. But that is okay if you don’t want something enough. The effort doesn’t have to be 110% for everything.
They expressed so much in this video that if there is a goal, a line, a dream, anything that you want so greatly, so bad (like you need air) – you need to work for it. Its definitely not good if you slack off since the only real person your letting down is yourself, and you get in a bad place. That is the point.
I thought sometimes, and experienced about failures and its stinks, since time and time again I mess up and confirm that I’m not perfect and its an impossible, unachievable goal (unless with some comic-book twist). But this isn’t a comic and that author can’t be relied on. So the question is: how to keep going?
I know I’m late with this post (ha, this is an example of a failure), so after I cringe and taste the humiliation, I might just stop posting in shame; but its the only thing stopping me from gettin’ it done. If I didn’t want this enough, I wouldn’t keep posting; I might even stop going to class if I didn’t care enough. But I do, I do care because I still learn. I like to learn and forgetting one assignment isn’t going to make I huge difference if I get better at posting ontime.
Elon Musk – Against All Odds is a video that addressed this. Featuring Elon Musk; one of the major players in leading the world’s advancements in technology, and we all assume that he got there in one shot; until he recounts his life story before he begun building Tesla – the electric energy company we all know; and the set-backs with his second company – Space X.
The video was a fresh reminder for me that people who seem successful, weren’t born or given something successful and didn’t have to go through any trouble; and then they broke the ice with Musk. Since its inspiring and encouraging to see that no one is hopeless at achieving success. After watching the video; there is with out a doubt, at least once in peoples lives, did they think they can’t do something because they aren’t rich, famous, seemingly talented like those they idolize or so stuck that they gave up. But really, the only difference is the time and place. Successful people are where they are because they worked, they kept trying; they cared enough to achieve their goal and understood what was necessary to get there.
How was the concept of gravity realized, and how is it measured?
Gravity is defined to be the force by which a planet or other body draws objects towards its center. The same force that allows for planets in our solar system to orbit the sun, or what makes things fall on the ground here on Earth.
How was it discovered?
In the 1600s, the concept of gravity was realized when Isaac Newton witness a falling apple from a tree while he thought about the forces of nature. He developed the theory that defined gravity as a universal force acting on all matter, the farther apart two particles are and the less mass they have, the less gravitational force they posses. The theory was left unchallenged for 3 centuries, until in the 1900s Albert Einsten extended Newton’s theory with his general theory of relativity. He argued that gravity was more than just a force; it was a curve in the fourth dimension of space and time. Given enough mass, an object can cause a straight beam of light to curve, this effect is what astronomers call gravitational lensing, which was one of the methods leading to the discovery of black holes.
Here is a video explaining more about Einsten’s theory of Relativity >>
How can gravity be measured?
It was said that the greater the mass and the closer together, the more stronger the gravitational pull, so with that how exactly were they able to determine the strength of gravity on Earth? It was assumed that the acceleration of a body due to gravity is a constant 9.81 meters per second squared, by every square meter gained toward the planet’s centre, the faster the object goes down. However the assumption would be considered true only if the planet was completely smooth and contains equal amounts of elements and minerals. Earths consists of mountains, caves, difference in terrain, oceans, valleys, etc, all containing different amounts of mass which influences the gravitational pull in different regions.
One of the way to find where on Earth is gravity the strongest or weakest, in 2002 NASA and German Aerospace Centre launch a joint mission names GRACE (short for Gravity Recovery and Climate Experiment), sending 2 satellites into the same orbit around Earth. One about 220 kilometers (137 miles) in front of the other at an altitude of 460 kilometers (286 miles) above the Earth’s surface. As the leading satellite passes over a stronger area of gravity, it would detect the gravitational pull and increase in speed slightly, thus decreasing distance from the tailing satellite, and the opposite happens when the lead satellite passes over a weaker gravitational pull, having distance increase between the satellites. The changes in distance between the satellites are very small– about one-tenth the width of a human hair — that they are undetectable by the human eye. GRACE measures these changes by generating pulses of microwave energy — a highly energetic form of electromagnetic radiation — that bounce back and forth between the two satellites. The distance between the satellites is determined by the time a microwave pulse takes to travel from one satellite to the other and back. Along with this, GRACE maps the entire gravitational field of the planet every 30 days, and with changes in gravity happening over time reveals detail about polar ice, sea level, ocean currents, Earth’s water cycle and the interior structure of the Earth.
Overall, one of the studies of gravity involves a branch of Quantum Theory, which is known as quantum gravity, in which scientists attempt to generally relate to each other. Quantum Theory refers to how does the universe work in the smallest level (subatomic) and it helps scientists develop standard models for particle physics which details more about the inner workings of the universe. However quantum gravity has one exception – it doesn’t explain much about gravity.
Both theories of Quantum Theory and relativity do explain most about the observable universe (the “horizon” of the universe we are able to see from Earth), and contradict each other like in the study of black holes. Not unexpected, numerous scientist do continuous work toward a unified theory. Whatever theories are adopted, it is difficult to overstate the importance of gravity, it is the glue that holds the cosmos together, even if its leaves unanswered questions about the universe.
