How to make agar

Making agar to grow your cultures is like making jelly!!
the ingredients needed are:
1.a vegetable or chicken stock cube
2. 1/2 teaspoon of sugar
3. some gelatin
4. 250ml of water
That's about it!

instructions:
1. Wash your hands to remove any contaminations.

2. Take a deep pan, put it on the stove and turn up the heat on pan. pour all ingredients in it and stir well.
    let it boil for a few minutes until no lumps are left and then simmer for 30 mins.

3. pour the mixture in your petri dish or petri dish like think and cool in a fridge to let the liquid become jelly.

4. Keep the dishes upside down to stop moisture forming on it and store for later use.

So literally I told you a chicken or vegetable jelly recipee. Enjoy the jelly or grow stuff on it. 

Synthesis of chloramine and hydrazine.[TOXIC, HAZARD, NEVER DO IT]

This experiment is based on producing hydrazine( N2H4 ) in liquid form and producing chloramine( NH2Cl ) in gaseous form.
BTW this experiment is dangerous, I havent done it.

First we gather the equipment!
we will need
1. sodium hypochlorite( NaClO )
2. Ammonia solution( NH3 )
3. A flask
4. two stoppers with one pipe through it
5. a connecting pipe
6. a test tube
Now we set up our equipment:
The reaction will occur in the flask, the hydrazine will stay in the flask while the vaporous chloramine will go in the test tube due to the pressure created.
Now we do the reaction, thought the hydrazine will be polluted with many other chemicals and the chloramine will be with water vapour.

how to find the kinetic energy of a proton

A proton has a radius of about 1 fm (10^−15 m). Use dimensional analysis with the speed of light c=3×10^8 m/s, the reduced Plank constant ℏ=1.1×10^−34 Js to estimate the kinetic energy of quarks inside a proton. Recall the conversion between Joules and electron volts, 1 eV=1.6×10^−19 J, and that MeV = mega electron volts, i.e. 1 MeV=10^6 eV.

Note that the point of this problem, and similar ones, is not just to do some conversion of numbers. The point is that once you know one scale (in this case a length scale---the size of the proton), it encodes a lot of information and characterizes the typical scales in the system (in this case the length scale also sets the energy scale).

so we have :
$$R=1fm(10^{-15}m)$$
$$c = 3*10^8m/s$$
$$h{bar}=1.1*10^{-34}J*s$$
$$V=1eV=1.6*10^{-19}J$$
$$1MeV=10^6eV$$

so we need a answer in MeV:
first we get a value in J*m:
$$a=c*h{bar}=3*10^8m/s*1.1*10^{-34}J*s=3.3e-26J*m$$

Now we need it to be in joules only:
$$b = a/R=\frac{3.3e-26J*m}{1*10^{-15}m}=3.3e-11J$$

this value to eV:
$$D = b/V=\frac{3.3e-11J}{1.6e-19J}=206250000eV$$

Finally this to MeV:
$$ANS=D/1e6=\frac{206250000eV}{1e6eV}=206.25MeV!!$$

Did I see a UFO

When I was in my granparents house then on 14august I went on th roof with the camera to picture the moon, on my side  I saw to lights revolving around each other and moving in a horizontal line back and forth, sometimes three lights appeared or sometimes 1 light, on the opposite side their were to more lights doing the same motion, so I took a picture or pictures of them but it was very difficult, successfuly I took 4 or 5 accurate photos which I enhanced:



it cannot be laser lights because whatever the light source was, it was above the clouds
it cannot be a ballon because balloons doont glow(it is brighter than the pics), not a lantern because no one knows about them in pakistan, BTW there is a military base near the house, its no spotlight too.

Changing matter into energy

So like Einsteins $$E=mc^2$$ formula states that if we have any mass (m) we can convert that mass in an energy by multiplying it with the speed of light(c) squared. I read on some area that if we add 90megajoules of energy to an object then its mass increases by 1microgram!, If you see a chunk of R-candy and give it an amount of heat energy, it will start to combust and while it combusts it will lose its mass and dissapear, only abit of burnt thing is left(1/20th o the mass), So my idea is that if we give A large amount of energy in a specific form, maybe we can change the mass to energy, so like if we have 1kg of mass, einsteins formula says multiply by $$c^2$$ so maybe we collide the mass with photons with the energy of $$c^2$$ or maybe somme 300000000 photons and we can change the mass to energy,

White holes! and anti-gravitons

White holes are like anti black holes, black holes want matter to come to the event horizon and then suck stuff up but white holes dont want anything to ever cross the horizon, nothing goes out of a black hole and nothing goes in to a white hole, its like blackholes have gravitons and white holes have "anti-gravitons", like super anti-gravity!!, like if a blackhole ate a star in and a white hole is connected to that blackhole and well spits out the star in a non-star form, probably gas. im saying is that the black-hole's singularity is even the reverse singularity of a white hole, time for a picture:

now anti-gravitons are what cause anti-gravity, not the non gravity but the repelling gravity in the white holes another pic:

Or maybe when they die out by radiating for a long long time, then they turn to white holes?

Drake Equation




This is the strangest but simplest equation I have seen, $$N=R^{*}*f_p*n_e*f_l*f_i*f_c*L$$

R* = the average number of star formation per year in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fl = the fraction of planets that could support life that actually develop life at some point
fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time for which such civilizations release detectable signals into space

the original values were like this:

R* = 1/year (1 stars formed per year, on the average over the life of the galaxy; this was regarded as conservative)
fp = 0.2-0.5 (one fifth to one half of all stars formed will have planets)
ne = 1-5 (stars with planets will have between 1 and 5 planets capable of developing life)
fℓ = 1 (100% of these planets will develop life)
fi = 1 (100% of which will develop intelligent life)
fc = 0.1-0.2 (10-20% of which will be able to communicate)
L = 1000-100,000,000 years (which will last somewhere between 1000 and 100,000,000 years)
So if we put in the values:
first medium:
$$N=1*0.3*4*1*1*0.15*10000$$
$$N=1800 civilizations$$

Then small:
$$N=1*0.2*1*1*1*0.1*1000$$
$$N=20civilizations$$

Then even smaller:
$$N=1*0.001*0.02*0.1*0.05*0.1*500$$
$$N=0.000005civilizations$$ we are alone

finally larger:
$$N=1*0.5*5*1*1*0.2*1000000$$
$$N=50000000civi...$$

Now for aproximation:
$$N=\frac{1800+20+0.000005+500000}{4}$$
$$N\approx125455$$civili....
