​The probability density function (PDF) of the normal distribution or Bell Curve of Normal or Gaussian Distribution is the mean or expectation of the distribution (and also its median and mode). 

The parameter is its standard deviation with its variance then, A random variable with a Gaussian distribution is said to be normally distributed and is called a normal deviate.
However, those who enjoy upskirts are called deviants and have a variable distribution :) 

A random variable with a Gaussian distribution is said to be normally distributed and is called a normal deviate.

If mu = 0 and sigma = 1

If the Higher Education Numbers Are Increased then the group decision making ability of society would be raised above that of a middle teenager as it is now
BUT 
Governments can control children by using bad parenting techniques, pandering to the pleasure principle, so they will make higher education more and more difficult as they are doing


85% of the population has a qualification level equal or below a 12th grader, 17 year old ... the chance of finding someone with any sense is low (~1 in 6) and the outcome of them being chosen by those who are uneducated in the policies they are to decide is even more rare !!!

Experience means little if you don't have enough brain to analyse it

Democracy is only as good as the ability of the voters to FULLY understand the implications of the policies on which they vote., both context and the various perspectives.   National voting of unqualified voters on specific policy issues is the sign of corrupt manipulation.

Democracy:  Where a group allows the decision ability of a teenager to decide on a choice of mis-representatives who are unqualified to make judgement on social policies that affect the lives of millions.
The kind of children who would vote for King Kong who can hold a girl in one hand and swat fighter jets out of teh sky off the tallest building, doesn't have a brain cell or thought to call his own but has a nice smile and offers little girls sweets.

Um ponto material percorre uma trajetória circular de raio R = 20m com movimento uniformemente variado e aceleração escalar a = 5m/s². Sabendo-se que no instante t = 0 sua velocidade escalar é nula, determine no instante t = 2s os módulos da:

a) Velocidade vetorial;

b) Aceleração tangencial;

c) Aceleração centrípeta;

d) Aceleração vetorial.

Simulation de la température au cours du temps d'une tasse de thé chaud dans lequel on met de la crème à un certain moment, qui peut être librement choisi.
Le challenge est de savoir si, pour garder le thé plus chaud, il vaut mieux mélanger tout de suite la crème, ou attendre le dernier moment juste avant de le boire.
La réponse est obtenue en changeant l'instant du mélange et en comparant les deux simulations à un temps donné (par exemple après 4 minutes).

Experiment - Can I use an agent model to do 1D heat conduction
Insight diagram

object is projected with an initial velocity u at an angle to the horizontal direction.

We assume that there is no air resistance .Also since the body first goes up and then comes down after reaching the highest point , we will use the Cartesian convention for signs of different physical quantities. The acceleration due to gravity 'g' will be negative as it acts downwards.
