notes Agricultural Energetics (by Richard C. Fluck and C. Direlle Baird)

 Agriculture industry geting energy from the sun and produce caloric energy. Energy cannot be created or destroyed - only converted. Conversion of electical energy to mechanical - usually has most efficiency. Fluorescent lamps have more efficiency than incandescent lamps. *but LED win!now Food is not only sun energy, but also oil, gas, coil - because of energy while development(and growing) agro system. Natural ecosystems run on solar energy. Incoming solar energy - solar constant 1.395 * 10^-3 MJ m^-2*s^-1 After calc without darkness, clouds - beetween 0.09 to 0.29 30% - directly reflected, 47% - converted to heat - only 0.02% for photosyntesis. Energy from plants -> Animal muscle energy. Man need - ~10.46 MJ. Possible to calc from where and how much energy man is getting. The Agriculture society next from the hunting society. Old agro societies - energy from the sun, labor people and animals. In industrial societies - sun and mostly oil energy. *Energy efficiency of society, E...

notes Vernadsky "Biosphere"(Вернадский "Биосфера")

Energy, energy of the sun Matter, live-matter Limits of reproduction by environment, adaptation in variety of forms Green live substance, in the ocean more quantity than on the ground “Sub beam creates” green matter, transfer energy for work. Work – as a reproduction, creating of green matter, “transformation” of energy. Big organisms more effective in the creating of green substance – small organisms are getting the limit very fast. Green matter has maximum efficiency – but human can regulate it by cycles. Also green matter changes their color in the deep – when need to adapt. *prochlorococcus CO2->O2 https://education.nationalgeographic.org/resource/til-20-our-oxygen-comes-bacteria/ https://chisholmlab.mit.edu/protocols/culturing-prochlorococcus-synechococcus-sar11-and-marine-heterotrophic-bacteria/ https://pmc.ncbi.nlm.nih.gov/articles/PMC4256842/ + carbon capture and storage (CCS) Life vortices(tornadoes).

notes "The problem of space travel" Herman Noordung

  Preface Asteroids and artificial satelites have own speed and motion, possible to use this system for planning long travels(bases, pit-stops) Main fields of research while travelling: materials science, zero-gravity studies(also physical and chemical reaction with non-air space) Knowledge of mathematical,physical,technical 3 Most critical obstacle - gravity *Newton’s law of gravity For escape need F(escape) > F(gravity) *force of gravity of earth in theory will be in all points of the space(but sure very small if  far) 4 Law of inertia with centrifugal force is important( objects in space moves in ellipses, circles) Event in the surface of the Earth we have centrifugal force For every killogram of spaceship possible to calc needed energy and velocity for ascent *All object have gravitational force for attraction - if spaceship can be like a black hole then space will move to spaceship, i mean spaceship not must moving ownself but what if space will be moving to the spaces...

notes "computers in space" Tomayko

1. simulations 2. testing when prelaunch 3. automated launch 3. control while moving(also robots) gemini software(first computer in space):     executor   - execute programs of mission     prelaunch  - ground check     ascent     - launch     catch-up   - change orbit and intercept object     rendezvous - closing and keeping     re-entry   - return program *first machines was with permanent memory(without delete) for safety in calculating possible use three machines simultaneously and check solutions with each other while calculating(2:1 voting) embedded computers - onboard computers in space craft *like a controllers for parts in the rocket, for example for engine launch **monitoring own part and run/stop - also under control of outboard system !vector mathematics deep-space missions: -launch -midcourse maneuver -cruise -encounter *onboard com...

Understanding earth is sphere: Shadow of the earth in the moon Polar star - comparing near equator and far Ships process of showing above horizon Calculating the circumference of the earth: https://www.khanacademy.org/humanities/big-history-project/solar-system-and-earth/knowing-solar-system-earth/a/eratosthenes-of-cyrene *we take two places - first without shadow second with skew shadow, we take measure between places(L), and angle of second shadow(A) then calculate A/360 = L/x Understanding circles/ellipses moving of planets: Nicholas Copernicus https://www.spitzinc.com/blog/solar-system-scale-copernicus-method/ *we wait when planet for observation will take a farrest place from the sun - this position gets us opportunity to calculate: line(main line) from earth to planet of observation is tangent of circle trajectory of this planet around the sun, angle between this line and sun is 90. We know angle between main line and line from earth to sun(main angle), and we can calculate lengt...
