A simple tutorial on predicting the chance of a heart attack using Machine Learning algorithms


Reading time: 4 min 2 sec Can machines learn just like humans do? If that is possible, will that be a threat to humanity? You might have seen apocalypse-themed movies and shows such as Terminator series or Westworld wherein intelligent machines become sentient and eventually turn against humans. Will such scenarios ever become a reality in the future? No one knows for sure. Whether such … Continue reading A simple tutorial on predicting the chance of a heart attack using Machine Learning algorithms

“Your reality is what you expect!” -How the brain manipulates our vision?


Reading time: 3 min 49 sec How do we watch a beautiful sunset or a thriller NetFlix movie? I mean, what’s the mechanism behind vision? The answer is high school stuff, isn’t it? A stream of photons hitting on our retina, generating electric impulses to communicate with our visual cortex from where the brain constructs a visual form of an irrefutable reality around us. Right? … Continue reading “Your reality is what you expect!” -How the brain manipulates our vision?

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.”

“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:
