About the book "Hidden Figures" (Margot E. Shetterly)


https://gamesandtehories.blogspot.com/

Kimmo Huosionmaa

In 1960's NASA hired black American female teachers to make calculations for the Moon program, and those women were in the key role to making the moon flight possible, we must realize that this book is not telling the stories about the women who made an extremely important job for NASA. It tells the story that there are more men and women who are played in the key role in many fascinating and awesome missions on Earth. Those women were in the key role in ending the racial separation, and the advancing equality between genders. In the modern day, every position of the persons should depend on the personal skills, without the influence of gender or the color of the skin. 


The technical staff is not many times mentioned in the texts, what are told about space- and other programs. But when we are going to deep inside those missions, and the history of calculations, we are facing the thing, that in those times, there were no calculators, and the major question is that who makes those calculations, what is always needed for many technical missions. 


Many of those men and women, who made the atomic bomb possible in the "Project Manhattan" are ever mentioned in the stories about this weapon. And in the history of Cryptology, there are no mentions, how the formulas and calculations of the Enigma's positions were made. If some persons are saying that computers are making the calculations, that person forgets something. 


The calculation formulas are always made by the programmer or mathematician, and then everything would be perfect. But without those formulas, the computers are unavailable to make calculations. Even the computers have the most powerful processors in the world, they have no capacity for productive thinking, and they need a man to make those formulas for the calculations. 


There were many claiming that NASA used also autistic persons to make those formulas, what was very important for the Apollo program. If the main motor would not be started precisely right time, the spacecraft would be crushed to Moon or Earth, or it could fly pass the object. Those things were very important for Apollo mission successful passing. 


Apollo-astronauts made the awesome job, but there were many people, whose names were ever mentioned. Those persons worked for motors, airlocks, ventilates and electronics. Many people in the world have ever seen the names of those persons, whose successful work was addicted to those formulas.

When legends meet: Laplace and Napoleon

Pierre-Simon Laplace
(1749-1829)
Picture 1


When the mathematician Pierre-Simon Laplace and Napoleon Bonaparte met the Emperor of France said, that there were no mentions of the god in Laplace’s papers. And the scientist answered that he didn’t need that calculation. I think that Napoleon was not interested in the god or mathematics when he met Laplace. The thing what interested this man, who became the figure of excellent tactician and military leader was something that was drawn in the papers of Laplace.



That thing was the points, what were drawn on those papers, and the way how Laplace could calculate them in the paper. If Simon Laplace could do the same thing for the artillery, French army will have the most lethal cannons on the battlefield. For many people, those points on the paper were nothing more than just the points. But as we must see, Napoleon saw those things by the different way, he saw a very effective way to use artillery.


Those calculations what made the finding of planet Neptune possible were known as the mechanics of heaven. The idea of the celestial mechanics was that Universum is a very stable place, where all particles move stable trajectories. This made possible that the movements of the particles can be calculated very sharply

The planets are found near the ballistical area of the sky, what is called as elliptical, and there is possible to calculate the point, where the planet will be fine with very good sharpness. Problem with the celestial mechanics is that will work only in the universe, there is no wind to disturb the planets, and if the conditions are the same kind in the Earth atmosphere than they are in the empty space, we could calculate every flight trajectory same way, what the astronomers used to calculate the points of Neptune.





 The thing is actually possible on the Earth if those calculations were involved more values, what will help in that calculation. First one is the side wind or the position where the wind comes, the second one is the temperature, the third one is the air pressure, fourth value is the humidity because the air what has particles will cause the changing of the ballistic situations. The sharpness of those calculations depends on how many vectors and values quantities could the mathematician involve the formula, what calculates the point, where the ballistic form ends, and those things were interested in Napoleon, who wanted to take the control all the Europe.

Leaders of government needs crystal ball

Everybody wants to see future. Leaders of government really need crystal ball to support their work, but there is some methods to forecast reactions of societies. There are two methods to forecast what will happen if we do something  mathematical and historical. They are not very trusty and some scientist think that some day we can build crystal ball what basis an electromagnetic black hole, what is created in NIF-type fusion test system. Last one is just reactor, where full geometrically made ball shape bite of metal or crystal will pumped with electrons or lasers, and then scientist could open wormhole to the future. That's possible in theory, but it needs other black hole in that target time, and those black holes oscillation must synchronize together. This way to see future through wormhole is theoretically possible, but making that machine is difficult because power what is needed is very huge.


When leaders of government makes their decisions you must realize that those people cant't see what really will happen in the future. They must just forecast what kind of influence is about those decisions what they make, but normally they can just imagine what could happen if they do something for laws or other things like international relationships. Of course there is tools what makes those forecasts easier, and one is mathematical method. There is formulas what are made for calculating massive gas masses movements, and those mathematical formulas are normally used by meteorologists when they want to forecast weather. Those formulas are useful to calculate people reactions for some decisions.


The idea of use of this kind of mathematical functions to forecast people reaction are basis on Science fiction book "The Foundation" what is written by novelist Isaac Asimov. In his book methodology was called "Psychohistory" The principle of use those meteorological or normal temperature pressure (NTP) formulas for sociological forecast is same as calculating  movements of massive gas masses. We can't calculate place of single atom, but we can forecast movements of giant gas mass, and calculating this kind of movement is easier for bigger masses of material than tiny mass.

Could NIF-reactor be tomorrows crystal ball?

That's because giant gas mass will not change direction of moving so easily than tiny mass of material elements. You see this in snow. Single snowflakes will move without sense but when we see snow falls we will know where it is going better when mass of moving snow is big, when even trees cant resist it power. And humans are like snow. We can stop one person of society, but problem is how we will find him. If all members of society will begin to move, we can forecast their actions, but they are harder to stop.


What is threat of society? Single group of people can't make our society unstable, but if many radical organisations are activating in same time, could result be devastating. That's why we have historical method to find out what our decisions can cause for society. It basis investigation of historical and political elements of crisis. In this method scientists will investigate history, and find similarities between historical decisions and decisions what leaders are making now. After that they investigate what influence that decision had to society.



After that they might want to inform leaders about dangers of some decisions. Methodology is not very sharp and it is not very trusty. But these unreliable methods are better than nothing. Of course scientist think that they can make tiny wormholes to see the future, and those wormholes are made with lasers or electric accelerators, what pump lots of energy to small target. Those systems might look like NIF, but I don't know is that technology tested in real life. And if they are right they could make small wormhole, what is smaller than atomic nucleus, and those wormholes could bring light from future like some light cable. And if everything goes right those scientist could theoretically make camera obscura what sees to future. But this is only theory.
