I need to create artificial waterbodies -containing clean rainwater- few hectares- and more or less cover it with THICK algae/plankton FAST- to provide food and oxygen for aquatic creatures as well as thick humus layer to areas irrigated with this water. The natural process is very slow. Can you help?
Are there algae/plankton seeds available that dont harm water quality/aquatic life and propagate real fast?

Y do u think the aliens are so worried about Earth? Don't u think they are real? They know exactly what would happen if the current human behaviour continues and they might have experienced the same thing in their world?

People will come back and do EXACTLY the same in life again, and again, and again for all eternity because the Universe started with the big bang which is still ongoing and the universe is still expanding, once it reaches as far as it can go it will start to contract and end up back to near nothing ness, after which the big bang will reocur again, starting the process once more, and everything you have done in this life will be repeated over and over and over for ever.

Growing up I loved science museums, but I already knew I had a love for science when I was very young. It is hard for me to say which came first. do you think science museums can make a kid interested in science or do kids interested in science like science museums?

pythagoras claims it is sound, or the simple octave, to make a long logic thread short it goes fludd to kepler to newton to einstien all who built theories on the foundation of each other which is based upon pythagoras concept of sound as the basic number of the universe and so to understand harmonic law is to under stand the numbers of the universe?

I heard that it would kill you by replacing every H in your body with D, but how is that possible since D2O is made by distilling water over and over again to concentrate HDO?

a) Astrophysics, astronomers and nuclear physics’: light, mid atomic waves caused by the electrons’ ups and downs inside the atom
b) Tarcísio Brito’s (self-taught scientist): Grand Atom (Universe) divided into three powers: Protons, Electrons and Neutrons. The sun contains the positive power (Protons), but with negative feedback (Electrons) and the Interstellar System contains the negative power (Electrons), but with positive feedback (Protons). Planet Earth is responsible for the Neutrons, acting in order to unbalance positive and negative powers in its limits. Therefore, neutralizes beginning and end. And so energies come from the place where they go to, and go to the place where they came from.

A time-varying net force acting on a 6 kg particle causes the object to have a displacement given by:
x = a + b t + d t^2 + e t^3
where a = 2.1 m
where b = 1 m/s
where d = - 2.3 m/s^2
and e = 0.97 m/s^3
with x in meters and t in seconds

Find the work done on the particle in the first 2 s of motion. answer in J
