Welcome to Science4All
My name is Lê and I believe that the greatest challenge in education is to make science and math appealing.
This is why I aim at bringing enthusiasm and excitement to the readers’ learning experience.

Bayesian Games: Math Models for Poker
Bayesian Games: Math Models for Poker
By Lê Nguyên Hoang | Updated:2016-02 | Views: 5627
How to better understand Poker and card games in general? Bayesian games provide the right mathematical model just for that! These correspond to games with incomplete information and include probabilistic reasonings.

Type Theory: A Modern Computable Paradigm for Math Type Theory: A Modern Computable Paradigm for Math
By Lê Nguyên Hoang | Updated:2016-01 | Views: 9997
In 2013, three dozens of today’s brightest minds have just laid out new foundation of mathematics after a year of collective effort. This new paradigm better fits both informal and computationally-checkable mathematics. There is little doubt that it will fundamentally change our perspective on rigorous knowledge, and it could be that, in a few decades, the book they published turns out to be the bedrock of all mathematics, and, by extension, all human knowledge! Have a primer of this upcoming revolution, with this article on type theory, the theory that the book builds upon!

The Essence of Quantum Mechanics The Essence of Quantum Mechanics
By Lê Nguyên Hoang | Updated:2016-02 | Views: 8698
Quantum mechanics is the most accurate and tested scientific theory, Its applications to real life are countless, as all new technologies are based on its principles. Yet, it’s also probably the most misunderstood theory, because it constantly contradicts common sense. This article presents the most important features of the theory.

Darwin’s Theory of Evolution Darwin’s Theory of Evolution
By Lê Nguyên Hoang | Updated:2016-01 | Views: 12641
Darwin’s theory of evolution is one of the greatest of all time. It’s also one of the most controversial. This article presents the most fundamental concepts of the theory. We’ll also provide results of modern science and discuss to which extend to they confirm Darwin’s postulates.

Self-Reference, Math Foundations and Gödel’s Incompleteness Self-Reference, Math Foundations and Gödel’s Incompleteness
By Lê Nguyên Hoang | Updated:2016-02 | Views: 3906
Although highly appreciated by artists, self-reference has been a nightmare for mathematicians. It took one of the greatest, Kurt Gödel, to provide a better understanding of it. This article deals with paradoxes, recursion, fractals and Gödel’s incompleteness theorems.

The Triangle of Power The Triangle of Power
By Lê Nguyên Hoang | Updated:2016-10 | Views: 2902
Notations do not matter to the essence of mathematics. But poor notations can be misleading. Notations based on exponents, radicals and logarithms definitely are. They are very distinct, even though they are supposed to describe very similar relations between numbers. The triangle of power is a recently proposed alternative. In short, I am convinced!

The Unlikely Correctness of Newton’s Laws The Unlikely Correctness of Newton’s Laws
By Lê Nguyên Hoang | Updated:2016-02 | Views: 4652
Do moving objects exhaust? Does the Moon accelerate? How strong is the gravity pull of the Moon on the Earth compared to that of the Earth on the Moon? While we’ve all learned Newton’s laws of motion, many of us would get several answers of these questions wrong. That’s not so surprising, as Newton’s laws are deeply counter-intuitive. By stressing their weirdness with Veritasium videos, this article dives into a deep understanding of classical mechanics.

Logarithms and Age Counting Logarithms and Age Counting
By Lê Nguyên Hoang | Updated:2015-12 | Views: 3524
Amusingly, the age difference between a 45-year-old man and a 25-year-old woman doesn’t seem as big as the age difference between them 20 years earlier, when the woman was a little 5-year-old girl. This remark was the insight the late science popularizer Albert Jacquart liked to give to his readers to explain logarithms. This article pays tribute to the great scientist by introducing age difference as he liked to tell it.

Beauty, the Driving Force of our Quest for Truth Beauty, the Driving Force of our Quest for Truth

According to Matthew Colless, the most important aspect of science is beauty. Not only is it what inspires scientists and their quests, I’d even claim that it’s also the compass that guide them in their quests, in a deeper and more surprising way that one can imagine!
