The Singapore maths puzzle.

Now that I could lean back I guessed the answer for this puzzle after reading it a couple times mindfully. I think the answer is August 17. WHY? I will explain in detail. But first of all the answer I came across here (in NY Times) is obviously misleading and incorrect. They give July 16 as the answer, but their method is wrong because they eliminated both May and June and there isn’t enough information for such a step. What they should do is eliminate May 19 and June 18. Because these two dates (18, 19) are not duplicated in the list of dates.

Once they did so it would be clear from the conversation between Albert and Bernard that June 17 could also be eliminated. Because since Albert knows that June 18 and May 19 are not good candidates for DOB, neither can June 17 be. If June 17 was the date he would not claim “I don’t know the date of birth” because he already knows the month and there is only one date in this month that is June 17.

The ambiguity of Hiragana and Katakana letters.

This article is to exemplify the ideas. The comprehensive version might be added given to a technically visible chart making.

These are the 5 hiragana (HG) and katakana (KK) letters that are almost same;
HG (や か り に へ) = KK (ヤ カ リ ニ ヘ ).

So if you know one the other will be a hackjob.

But that won’t be too many. I am rearranging them into groups so it will be really easy for you to remember the alphabet in a few hours.

There is only one physical favor the Universe did on life.

But all of them are not stable. We have made great strides in understanding them collectively called as standard model of particle physics which involves electroweak and strong interactions. Its a weird mess of beautiful list of particles and their behavior toward each other. Sometimes there is symmetry breaking sometimes there is symmetry and sometimes there is confinement.

What such an astounding theory backed by the most swashbuckling experimental measurements have meant is there are only countable number of stable particles.

Let’s begin counting out of 100s electron, proton, photon and neutrinos … That’s it. End counting.

It explains almost everything we see around us. The matter. If we are to see dark matter we would be explaining that as well. But hold your breath we haven’t seen that so far.

Since almost everything we have seen are so unstable we wouldn’t be created.

But the very few stable particles made atoms possible and the atoms made life possible.

Here is how the atom is possible.

The neutron guy is not very happy as its not stable. It met proton on a blind date and they got

Addendum to Coriolis Force; Definition of Centripetal Force.

We need to understand first that Force can be categorized into two types. One is called tangential or collinear force. This component of the force is always along the direction of motion and changes speed of an object. It can change direction once the velocity of the object has become zero. Its NOT centripetal force. It can never make an object go in a plane or 3 D trajectory, as the motion is limited to only one dimension. The object can only go back and forth.

Now look at the other component. Its called a radial force. Its always perpendicular to the direction of motion. This force is called centripetal force, always. Note that its different from what we call central forces.

In consequence, both tangential and radial forces can be central.

Quantum Entanglement .. a short primer !

This fact is inherently, nothing but the concept of Quantum Entanglement. Unlike classical particles which are completely independent of each other the quantum sized objects are not. For physical intuition they are at a very small and subtle level intertwined with each other as if threads are kind of tied onto each other. We can-not toss an electron because the whole concept of one electron completely independent of all other makes sense only when all other electrons are not interacting because they are arbitrarily far away.
