Way mathematics is taught, need a disruptive change

Mathematics needs a disruptive change, students who are not better problem solvers in all other fields are bad in it.

UNDERSTANDING how the calculation works is the most important step to test and analyze a problem.

A most common problem with students who are scared of mathematics is not understanding how fractions work.

What will happen if you divide a decimal number between 0 and 1 with 1000 and 10,000 etc?
What will happen if you multiply it with 1000 and 10,000 etc.?
What is the meaning of 1/3 * 1/4? What is actually happening in it?
How to divide a smaller number, for example, a decimal number between 0 and 1,  with a bigger number? What are you actually doing in this way, how will you explain it with the example, such as a cake or tiles?
How to subtract a decimal number between 0 and 1 with a number greater than one?

Fractions are everywhere, you will find not a single field in which you will not find its (mathematics) application, whether you do physics, chemistry, biology, statistics, psychological studies, computer science, economics or any field.

Mathematics is not "all about memorizing rules", it's about understanding why and where the rules work.

If you pay attention to understanding, a student will find mathematics more interesting and always try it to apply in real life situations. Memorizing rules are also taken cared of indirectly.

Need a disruptive change in how mathematics is taught in class, so that they understand why the rules work and what and where are its applications.

Bacteria and Competition: How it's similar to human? and Why we should have family planning?

Image
Growth of the bacteria refers to an increase in bacterial numbers When bacteria is grown in a liquid nutrient medium, the population is counted at many time intervals, and we get a bacterial growth curve that represents growth of cells over time. Why bacterial growth curve is so important? It gives the idea to learn about the impact of competition in the simplest way. It gives the answer what happens to a population when resources are limited. Bacterial growth best suits even to describe the human population. In science, there are 4 phases, but for simplistic understanding, without any scientific jargon it can be three stages: Thrive, Survive, and Deteriorate Image from wikipedia (A: Lag phase, B: Log phase, C: Stationary phase, D: Death phase) Stage 1: Thrive In this phase bacteria has sufficient resources, so bacteria flourish, prosper or grow vigorously. In science, it's the lag phase and log phase. In the lag phase, there is no cell division, but cells are not dormant, they und...

A new fair democracy inspired by Delegated Proof of Stake algorithm

Image
Preprint link: https://osf.io/82mpk/ dem·oc·racy [democracy democracies] 1) fair and equal treatment of everyone in a country or organization, etc, and their right to take part in making decisions 2) a system of government in which all the people of a country can vote to elect their representatives Yes, most democratic countries fulfill the second definition of democracy, but none to the first definition. Abstract: Democracy is about fair and equal treatment of everyone in a country. But it becomes unrealistic to achieve when political parties have their conflict of interest , and leaders don't have the expertise to make evidence-based policies and neither have the skill and manpower for solving problems that surround our society and ecosystem. The new fair democracy provides an elegant way of governance that separates the representative responsibility according to their specialization and can grow into any complexity. The governance is divided into various departments, and each ...
