A simple code to import and visualize COVID19 real-time data using COVID19Py python package


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

“Hey life, you take the breath out of me…”


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…”

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:

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.
