All for Physics by the expert

Hello Guys and welcome back to my blog !!! Today I am gonna post some easy but challenging Physics problems  (Advisory Content - Only to be solved by Physics Experts/Lovers) Universal Physics Expertise Problem #1   (TOUGH)   Calculate the Force Change if both the boxes are the same HINT  :To be only used if answer not found after full effort by trying Universal Physics Expertise Problem #2   (EASY) Values for calculating limiting friction are  mew s = 0.4  normal = 19.5 N Find Limiting Friction acting here Friction acting on the box (HINT - Mass= 5kg velocity = 0 m/s & F (l) = Mew s x N) a) If you have found the answer post it in the comments  b) If not wait for the answers with the explanation published tomorrow c) Tell me whether you want even tougher ones That is it for today  I will be back soon with more challenging physics problems Till the...

A beautiful quote by Paul Dirac Many of you physics lovers would have figured out what I am gonna talk about Yes, The contrary to matter - Antimattter So now let's have a brief insight about it Antimatter: Classical physics only allowed systems to have positive energy. But Dirac’s new theory of relativistic quantum mechanics allowed for a particle with negative energy solution, as a counterpart to the familiar positive-energy electron. After ruling out the possibility that this particle was simply the proton – which has a hugely greater mass – Dirac predicted the existence of a new particle with the same mass of the electron but with a charge that was positive rather than negative. It’s now understood that all particles have an equivalent antimatter particle with opposite charge and quantum spin – although some are their own antiparticle. However hardly any antimatter is seen in the observable universe, and why there should be vastly much more normal ma...

A beutiful quote on description of Science by Edwin Hubble Hello everyone and welcome back to my blog Today we are going ot talk about 'THE GENIUS' that changed the course of Cosmology So first we are going to talk about So gear up and off we go... 1) Hubble's Law Hubble's Law states that v = H o D wherein:-  v represents Velocity (IN km/sec)  H o  represents the Hubble’s Constant (Current Value is 73.8 km/sec/Megaparsec) D represents the distance to the galaxy (In Mpc) "It is a law stating that the red shifts in the spectra of distant galaxies (and hence their speeds of recession) are proportional to their distance" A red shift is observed when objects are moving farther from us and this law went against is ideas of Newton and others for a static universe A GIF on the Expansion of the Universe (Interesting Fact- Einstein refused to accept an expanding universe even though his theory proved so!!!) In hi...

A famous quote by Einstein on Humanity A representation of Einstein and his theory of relativity  So yeah, unlike yesterday we are gonna talk about a space prodigy who will never be replicated Today we are going to talk about a sensational breakthrough in the history of Astronomy i.e, The Theories of Relativity: Special Relativity  General Relativity  So let's start with a brief introduction on it In 1905, at the ripe age of 26, working in a patent office,  He produced the 5 papers that made the universe to get a new look, a lot more different than the ideas by Newton and others like static time.  Those 5 influential papers were: General Theory of Relativity  Spacial Theory of Relativity Brownian Motion Photoelectric Effect  Mass Energy Equivalence These papers changed the course of history Let us study 'Theories of Relativity' in detail General Theory of Relativity Einstein proposed that obj...

"The trouble with the world is not that people know too little; it's that they know so many things that just aren't so" Mark Twain Hello guys and welcome back to my blog Today we are going to talk about misconceptions induced in our mind by  Aristotle So gear up and off we go 1) ' Everything that moves, will eventually come to a stop. Rest is the “natural” state of all objects' Like seriously... Had he been alive for 2009 more years he would have suicided of guilt and tons of bruises on him for leading humanity towards the wrong way for 2009 years (Almost two millenniums wasted on wrong ideas) Newton's first law of motion was that "Every body in the universe continues to be in its state of rest or motion unless acted upon by an external force" Or in simple words "If the external forces on a body are balanced , then the body will continue to have zero acceleration due to which it will continually have constant velocity ...

"Curiosity is one of the permanent  and certain characteristics of a vigorous intellect" By Samuel Johnson  One of the curious doubts asked by a physics lover on "The Grand Old Universe" was :- ' Why it was difficult to get a picture of black hole earlier? What are the changes in technology that made it possible? '  I, The Physics Expert will crear that doubt in this post The answer is :- The work that allowed this photo to be taken has been going on for decades. It meant overcoming difficulties that have seemed impossible. The central difficulty with trying to get pictures of black holes is given away in their name: they are black because they have such a strong gravitational pull that light falls into them and can’t escape. As such, it can’t get to here and we can’t take a photograph of it. To get through all of that difficulty, astronomers had to work to join eight different dishes up into one huge virtual telescope, allowing the...
