If you’re trying to simulate free-field acoustic conditions using a pulse technique, then you might be facing a bunch of noise, including a large 1st harmonic, where you’re trying to measure only the second harmonic. Using a lock-in amplifier to cut out the noise is a common solution, but it accepts all reflections as well, …

Real World Applications of the Duistermaat–Heckman Formula The Duistermaat-Heckman formula is a mathematical formula used to evaluate integrals over symplectic manifolds. This formula has many real-world applications in various fields of physics, including classical mechanics, quantum mechanics, and quantum field theory. Classical Mechanics In classical mechanics, the Duistermaat-Heckman formula is used to calculate the partition …

Physics equations are grounded in the basic principle of motion. We use these equations to predict the position of an object in time after knowing its initial position, velocity and acceleration. The motion of particles is determined by external forces acting on them. Therefore, it is essential to understand the nature of these forces to …

Have you ever wondered why the magnetic field inside a solenoid does not depend on its radius whereas the magnetic field inside a circular loop or a coil depends on its radius? In this article, we will try to answer this question in simple language that even a 10th standard student can understand. So, let’s …

Understanding Phonon Frequencies in Solids When scientists study the physical properties of solids, they often look at the behavior of waves that travel through the material. These waves are known as phonons, and they play a crucial role in determining how solids behave under different conditions. Phonon frequencies are essentially the different frequencies at which …

Quantum mechanics, also known as quantum physics, is a theory that deals with the behavior of particles on a microscopic level. It was developed in the early 1900s and has provided scientists with a new understanding of the fundamental nature of matter and energy. But how does quantum mechanics apply to our daily lives? The …

Microwave Cooking: Experimenting with Poached Eggs Have you ever wondered about the science behind microwave cooking? If so, you might find the following experiment interesting. Suppose you are poaching a chicken egg in a small glass dish in your microwave, and you want to know whether two eggs will reach the same temperature as a …

Gas springs are a common type of spring that make use of compressed gas to exert a force. They are widely used in many different applications, from automotive suspension systems to office chairs. In this article, we’ll explore how gas springs work and try to answer some common questions about them. What is a gas …

When it comes to vehicles, brakes are undoubtedly one of the most important components. Without them, the vehicle would not be able to come to a complete stop, which could cause accidents and injuries. Interestingly, in the majority of cars, it is possible to see the location of the brake pads through the wheels. And …
