Physics (from Ancient Greek: φυσική (ἐπιστήμη), romanized: physikḗ (epistḗmē), lit. 'knowledge of nature', from φύσις phýsis 'nature') is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest. Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy, but during the Scientific Revolution in the 17th century these natural sciences emerged as unique research endeavors in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in academic disciplines such as mathematics and philosophy.
Advances in physics often enable advances in new technologies. For example, advances in the understanding of electromagnetism, solid-state physics, and nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

I am about to graduate with an aerospace engineering degree. I am planning to go into grad school for Applied physics(probably plasma physics), which I find very interesting. But the main reason I joined the aerospace degree was because I was interested in CFD. But since I could't land any...
yet another silly question but can you have a career as physicist and work in the afternoons or evenings? It has become obvious that I am not very productive before 1 or 2pm
1 A beach ball is thrown straight up with a speed of 10m/s from a point 2 m above the ground
a) Assuming no air reistance, calculate how far up the ball will go
b)At what speed will the ball eventually hit the ground?
c) If the air resistance exerts a constant force fo 10N during the...
Hello everyone, i just graduated from a Nigerian university with B.ed in Physics,but am more interested in becoming an aeronautic engineer. How is this possible? Though am very good with calculations (both in maths & physics) but has not had any tactical skills to that effect. I want to know...
Hi i just learned fluide equation form chen textbok
The equation is mn\left[ \frac{\partial u}{\partial t}+(u\cdot\nabla)u\right]=qn(E+u\times B)-\nabla\cdot P - \frac{mn(u-u_{o})}{\tau}. where P is pressure and last term is collision between charged particle and the nutral

Hi, I'm very interesting about Theoretical physics, In fact, I want to learn about Particle
physics for my desire to solve difficulty.
But, when I tried to study the famous mathematical book, by afken, I recognized it very hard
to study by myself.
So, I want to know other book...
Advancing physics c/w
hiya everyone,
i was just wondering if anyone else is doing the advancing physics AS level and could help me with the data anaylsis c/w. i don't even know where to start and don't even know wot i am meanta do wiv all these numbers. hehe please HELP!
