What do you think life would be without physics?
Without the understanding of physics today, many applications in physics such as electronics and mechanics would not exist today. We would be living without modern technology or instruments. A hammer, for example, would be well within our grasp, but things like the internet would be beyond us.
How hard is it to study physics?
Physics, itself, isn’t hard. What’s hard is that Physics is the first time that many students actually have to use their knowledge to solve problems as opposed to merely regurgitating facts. It’s not difficult to grasp physics concepts. It’s not difficult to solve the math.
Is it hard to be a physicist?
It’s very hard to be a physicist. The vast majority of physics grads never become one. Of my undergraduate class none of us were able to do it. You really need to open your mind or you will never be happy.
Can universe exist without gravity?
NO universe can’t exist without gravity! Gravity is one of the four fundamental forces which has a promonet role in macroscopic space just like electrostatic force has a prominent role in microscopic effect.
How is the universe without force?
In a universe without the weak force, the existence of anything other than stars would require more free protons and fewer neutrons (because they could not decay). Stars fueled by deuterium instead of hydrogen, the researchers note, would still shine, they would just look different—likely redder and larger.
How physics influence your daily life?
Physics extends well into your everyday life, describing the motion, forces and energy of ordinary experience. In actions such as walking, driving a car or using a phone, physics is at work. For everyday living, all the technologies you might take for granted exploit the rules of physics.
What are the best books to start learning physics?
The Feynman lectures on physics are beautiful books, which will teach you a considerable amount of the long-view of physics. They will also inspire you and have you feeling as though you really understand physics for the first time in your life. Mainly mechanics, radiation and heat is recommended for the start.
Is the Feynman Lectures on physics a good book to read?
The book is based on a series of lectures delivered by Feynman (on the request of California Institute of Technology) to undergraduate students. Even professors attended the lectures! The Feynman lectures on physics are beautiful books, which will teach you a considerable amount of the long-view of physics.
Why is Albert Einstein important to physics?
Albert Einstein was an intelligent man who discovered groundbreaking theories. He was a german who changed the world of physics. He created the theory of relativity. He’s done so much for physicists and the world. His death was nearly a centennial, yet he’s still one of the most notable, if not the most notable, physicist to this day.
