The mantra for getting things done
Reading time: 1 min 27 sec People often complain that they cannot get their things done on time. People say many reasons for this; they say that they are either stressed, overwhelmed or just not interested in what they do. I am pretty sure that you know at least a few people who keep on pushing their work to the future. Have you ever thought … Continue reading The mantra for getting things done
Building a realtime phase-space and timeseries plotter for a Simple Pendulum using Arduino Uno & Simulink

The contents are structured to enable you to do this DIY project by yourself! These days, it’s pretty much straight forward to simulate physical systems in a computer. Running those governing equations in any high-level languages such as Python, Visual Basic, … Continue reading Building a realtime phase-space and timeseries plotter for a Simple Pendulum using Arduino Uno & Simulink
The essence of meditation: “Live your life, moment by moment.”
Reading time: 2 min 2 sec People often mistake meditation as a religious act. It is imperative to demystify this common misconception about meditation. Meditation has got nothing to do with any God or religious entity. It is an astonishing fact that even in this modern age, the majority of us are not willing to approach meditation with an open mind. Such beliefs can act … Continue reading The essence of meditation: “Live your life, moment by moment.”
Finite and infinite conjugate objectives
Reading time: 1 min 2 sec An objective is nothing but a compound lens, like a normal lens, the only difference is they are much more potent in terms of numerical aperture, resolution and magnification. In microscopes, objectives are mainly used with two optical designs: finite or infinite conjugate designs. In a finite optical design, the light from a spot is focused into another spot … Continue reading Finite and infinite conjugate objectives
Taking Fourier plane out of an objective for angle-resolved measurements.
Reading time: 2 min 14 sec. We know that a simple lens is a Fourier transform engine, which does complicated ‘Fourier calculations’ of any object faster than any computer available today! An object placed at a distance d from the lens forms its Fourier image at the back focal length (f) of the lens. As we know, Fourier image is always formed at the focal … Continue reading Taking Fourier plane out of an objective for angle-resolved measurements.
How to screen a femtosecond laser pulse stream on an oscilloscope?
Reading time: 1 min 42 sec
It is quite possible to view the pulse stream of a femtosecond output on an oscilloscope screen, especially to measure the repetition rate of the laser. It is to be noted that, we cannot see the pulse shape of the laser beam as the response time (rise and fall time) of the photodiode (PD) is quite higher than the pulse width of the femtosecond laser.
Things to be noted:
Continue reading “How to screen a femtosecond laser pulse stream on an oscilloscope?”
Your mind and a car: An analogy
Reading time: 2 min 34 sec You know how a car moves. It takes a lot of force for an engine to start and accelerate a car. It consumes a lot of fuel during the process of acceleration. After attaining the desired momentum, it only requires very less power from the side of the engine. But then the air resistance and ground friction come into … Continue reading Your mind and a car: An analogy
How religion bends our thinking ability?
Reading time: 4 min 35 sec A few days back, I was in a friendly debate with one of my best friends. As usual, it was about the existence of God. He made this statement, ‘”Our eyes have a limitation in seeing objects. It can’t see smaller things beyond an extent. Our ears are also limited so that we can only hear in the frequency … Continue reading How religion bends our thinking ability?
Time to be smart: ‘Fact’, ‘Law’, ‘Hypothesis’ and ‘Theory’ in Science.
Reading time: 2 min 57 sec I recently watched a youtube video where Dr Zakeer Naik says to a bright medical student that a ‘theory’ in science will only become ‘law’ after testing and verifying its correctness using scientific methods. I got shocked listening to this nonsense. Here is a man with the title ‘Dr’ (physician, I guess) who is supposed to educate himself at least with … Continue reading Time to be smart: ‘Fact’, ‘Law’, ‘Hypothesis’ and ‘Theory’ in Science.
Overthinking and worries: Causes and solutions
Reading time: 3 min 37 sec A few days back, we were planning to go for a movie, and suddenly one of my friends raised her concern, “I am not coming. The road would be heavily busy, I hate it. I can’t handle it.” I exclaimed, “But you have come many times before.” It was her reply that made me write this post. She replied, … Continue reading Overthinking and worries: Causes and solutions
