Reading time: 4 min 2 sec COVID19 has almost put a pause on our everyday life; quiet roads, vacant parks, closed theatres, silent supermarkets, and the list goes on. To resume our life back to normal, it is inevitable to develop meaningful and scalable medical and technological solutions asap. In general, medical solutions such as vaccinations and other popular treatments can help our immunity system … Continue reading A simple code to import and visualize COVID19 real-time data using COVID19Py python package
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
Reading time: 1 min 42 sec (Contributed by an anonymous author who doesn’t want to reveal his identity.) Dear friend,That moment of bliss when you become one with your surroundings, you lose even the tiniest bit of importance in the grand scheme of things. Your existence no longer matters when you learn the answer to the eternal question, ” Why is there something rather than … Continue reading “Hey life, you take the breath out of me…”
Rational aspect of mind never creates anything; it only deduces from something which is already being created. It takes the irrational aspect (imagination) of the mind to create something new from nowhere! Continue reading Aspects of mind
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
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.

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:
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
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?
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.
