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....

Update on rocket: My first smoke bomb.

Im here in my grandmas house,(a small area in rawalpindi with 6feet wide roads and hundreds of houses and shops packed together) and in a shop I found fireworks, you set them on fire and throw them and they blow, they have a silvery powder in them,(possibly alluminium powder and some explosive stuff) so I found a empty marker with no head, it was quite roughly broken so I thought thats its junk and it will be good if I blew it up! So i stuck a firework in it and blew it, well it didnt disentegrate but the roughly broken part got smooth. I had some explosives left so I broke them from the middle which is a easy way of removing the powder, and I filled the pen with it and lighted the powder after many failed attempts of lighting it. well before that to seal it from one side I stuck it in a flower pot whichs dirst compressed and sealed it, continuing my hopes was that it will launch, another dude looking at me from another house tried to warn me that it will blow(he did not know that it had an opening:)), well it sarted glowing, melting and creating small holes which were like tiny volcanic eruptions of smoke, it wasnt much but the sight was pretty, well after it all ended it was like a sticky goey, melted pile of ash and melted plastic, the sight was like a wreckage so i decided to remove the pile from my sigh so I held it and threw but I did not know that the plastic was still cooling so it stuck itself to my fingers, after counntless attempts I removed it, it had solidified by taking my coolness, and in fact I was burnt for the millionth time, (the day before I was even burnt(always on the finger never any other part.)).

My thoughts on telepathy (c)

Since the we hear sounds because vibrations enter our ear through the outer ear going to the ear drum which vibrates, then the three bones(anvil,stirrup and hammer) magnify the sounds and send it to the cochlea, the vbrations move a liquid which moves tiny hairs to produce electrical signals send from the auditory nerve to the brain and we hear!, But what if we put something in the brain, like a reciever chip, and send a low frequency or a small signal, which gets itercepted by the brain directly, without the need of vibrations. One good thing is since the signals get sent at the speed of light, then someone can telepath from very far away.

BTW: The (c) is a copyright, I dont know if anyone has this idea or not, the only thing is I somehow just got this idea when I was sleeping last night.
