Second Law of Thermodynamics and Entropy

Khaleel Ashraf — Tue, 10 Oct 2017 05:51:44 +0000

In everyday life we experience many limitations on energy transfers. A hot bowl of soup becomes cooler, for example, but a cool bowl of soup never spontaneously heats up. The second law of thermodynamics is one of the fundamental theories of nature that explains this (along with many other things). The most intuitive statement of […]

Electricity and Electromagnetism – Part 2

Khaleel Ashraf — Sun, 22 Jan 2017 03:23:15 +0000

Electricity and Electromagnetism – Part 2 The beginning of electricity’s modern era can be traced to a small Danish classroom in 1820. There, in front of a room full of physics students, Hans Christian Oersted (1777–1851) discovered that electricity can produce magnetic fields. Oersted was the son of a Danish pharmacist, and he had planned […]

Electricity and Electromagnetism

Electricity and Electromagnetism Can we even imagine a world without electricity? But as unimaginable it may sound to us now, the story of electricity for practical use has been around for only few centuries. Most modern uses of electricity rely on electrons that move. Newton’s first law of motion demands that electrons can’t move unless […]

The First Law Thermodynamics, and the net energy of the Universe

Khaleel Ashraf — Wed, 19 Oct 2016 05:03:38 +0000

The first law of thermodynamics states energy can't be newly created nor destroyed; so where did the universe come from? Did the origin of universe require a super natural explanation? New understanding of cosmology however shows, despite our intuitions, the net energy of universe is 0 and the whole universe could indeed come out of the "quantum foam" of nothingness, according to Stephen Hawkins and others. A brief overview of the implications of this dramatic new insight.

The Nature of Energy Laws of Thermodynamics

Khaleel Ashraf — Wed, 19 Oct 2016 04:53:53 +0000

The study of energy is called thermodynamics. Unlike Newton’s laws of motion, the laws of thermodynamics did not spring fully formed from one mind. Rather, these ideas emerged gradually from the work of many researchers, and it was only later that they were set down in the form we now know.

Life’s Persistent Questions: Part 2

Khaleel Ashraf — Sun, 09 Oct 2016 10:06:18 +0000

Origin of a Malayalee (East of West, North or South Mallus are the best!!) Prevailing theory is that earliest humans evolved for several thousands in Africa before migrating out of Africa (In fact Africans are the most genetically diverse group, as can be seen in the difficulty matching HLA identical donors among Africans – as […]

Life’s Persistent Questions: Part 1

Khaleel Ashraf — Sun, 09 Oct 2016 08:05:10 +0000

Where do we come from? Is there a purpose to life? Where did the universe come from? Below is a short write up on how a rationalist can approach these “life’s persistent questions” – about origins, meaning and destiny. This is not meant to change any one’s mind – as I am least interested in “evangelizing” what I think is true as I believe every person is intelligent enough to have their own ideas about life, cosmos, evolution etc. But I request you all to read the point of view of a rationalist. Unlike the explanation of a religious person, who can explain anything in 10 seconds by saying “that is what my holy book says”, a rationalist argument takes time to explain, but way more interesting and intellectually satisfying.

Science, Scientific Method & the Beauty of Science Part 2

Khaleel Ashraf — Wed, 05 Oct 2016 07:18:18 +0000

This is the part 2 of the article “Science, Scientific Method & the Beauty of Science” Part 1 can be read from here By 1640, Johannes Kepler had derived the mathematical foundation for describing planetary orbits around the Sun, and Galileo Galilei had presented equations that predicted the behavior of falling objects. Yet, at that […]

Science, Scientific Method & the Beauty of Science

Khaleel Ashraf — Mon, 03 Oct 2016 15:03:36 +0000

Science holds a special place as a method designed to ask and answer questions about the tangible aspects of the physical world. Science is based on reproducible observations, controlled experiments, and theoretical reasoning. Science is fundamentally different from other ways of knowing because it is based on independently verifiable facts about physical phenomena, for example: […]
