Name: Archimedes
Date of Birth : 287 BC. M.
Date of death : 212 BC.
Notable ideas : Hedrostateka
Influenced by Euclid
Archimedes said if there were a focal point for the raised ground, and if there is any ground for the second moved to our land and moved from its place Yes it can, in theory, but there are considerations which Archimedes made a mistake you know?
(In fact the words of Archimedes is true only in theory in practice either Vmsthil some shortcomings and these are some of them /
1 - It will not be able to give a focal point of Archimedes
2 - It can not arm length, making billions of kilometers
3 - Archimedes needs millions of years to move the bracket arm for a distance of 1 cm
4 - as much as the laws of God in the universe which is fixed to the time will not be able to do despicable human beings to change these laws
(With great respect for Archimedes)
And the Earth, also fall on the apple ... Aanewton (Newton's third law of motion):
(Also this is true but the speed attracted the apple to the ground faster than the attraction of the earth to an apple, so the apple falls to the ground)
Asked the student teacher to understand that after the text of Newton's third law and said, sir, if the horse drag the cart and cart horse drag force itself, but in the opposite direction, it means that the vehicle will not move, then why do we see it moving?
Replied the teacher have forgotten your colleague that the two non Mtadeltin because they affect the two objects different: the former affects the vehicle and affect the second horse so the forces of equal if affected the body itself, the Newton's third law applies well but if affected the different bodies, each of which impact varies depending on the body and nature and on the amount of resistance of such a force against
May God have mercy friction:
After the teacher explained the meaning and importance of friction in walking and standing and wear clothes and fragmentation of the mountains and many others' asked the student, saying, What if there were no friction?
The teacher said if friction disappeared because I was able to hold a pen, and to still your foot is located on the ground ... There are many examples of
(If there is no friction of what I wrote to you this talk)
Gravity on vacation ... (the law of gravitation):
When thought of Columbus to cross the Atlantic Ocean, many people believe that the earth is flat Faqalo that Columbus would fall soon and the arrival of the edge and did not know that the earth is spherical or near spherical So that ended the teacher of his words until Badhirh question from afar say yes and only to the people who are at the bottom of the earth and walking their heads down and this can not be definitely how their lives then?
Said the teacher and the student come in front of your colleagues point to the bottom with his finger pointed to the ground and then said to him point to the highest heaven, he said, referring to the teacher if we asked the same question to students in a country far away do agree with you to answer the teacher said yes, he said, then down, which indicates him and referring to any other student is the center of the earth and the above is far from the center of the earth and this is the error that does not know many people
Sea do not drown when a (fluid properties):
Is there a student asked the Sea does not actually drown when a teacher said, sir Yes Sea is located in the occupied territory of Palestine and called the Dead Sea, but what a scientific explanation?
The Dead Sea is very salty so the water is heavier than sea water and the other reason it is impossible to drowning
Air defies sixteen horsepower (atmospheric pressure):
Said these words, what the teacher waited until the student objected by saying reasonable? Said the teacher was done in Regensburg, Germany, and the debtor in the presence of the emperor and princes where they saw a strange offer sixteen horsepower and is trying with all its power to separate hemispheres of copper joined at each other, but he asked the student what is the adhesive and you are present here?
He replied yes, the teacher considers it the air that many do not note anything that has weight and has the power of great pressure on all the things on the surface of the earth.
what did you like the sound (sound transmission):
ASK: I heard the sound of sitting in front of the speaker in the lecture hall, for example, or who sits in his home and taking the radio headset in his ear? We find that the listener hears from his home first, but yes, because how the electromagnetic waves that carry sound to the radio a million times before about the sound has moved away from the speaker to the listener is sitting in front of him in the hall
ASK: the sound slows down when his footsteps
What do you expect to happen to Losar sound less rapidly than the person Walker on his feet Yes I think I will say a word and then to listen to it Ospgaha of the other party and I expect that we can not interfere sounds to distinguish them
(Sound travels faster in the heat)
Q: The audio clouds
Did you know that sound can be reflected from objects, for example thin soft Kalgiyum Yes, we have discovered the world of that name coincidence when Tyndall was going on his experiences on the audio signals at the sea coast, he wrote: We are the echo of sound reflection from the air Sstah completely transparent. We have reached the echo from the clouds magically invisible voice and interpretation of those clouds is uneven heating of air currents, or that contain a different amount of steam
(Echo echo is a sound after 0.1 seconds of Asdrah, the object which is not only an echo of his voice is a duck)
And said the student, sir What will happen if the Earth stopped rotating suddenly? What happens
Said Professor / something serious happens there will be no houses or trees or the life on Earth because of inertia will cast them away from that surface and fly at speeds of the bullet on the line tangent to the Earth's surface and then fall down and shatter
Well ... What's her decision: - gravity
It is known that the deeper wells do not extend into the ground Elyokther of 7.5 km, but let's say that there is a well extends along the axis of the earth, from pole to another (half the diameter of the Earth 6400 km) and that someone has fallen into this Alair, which has no decision What would happen to this person if we ignore air resistance?
Student said: It will hit the rock bottom and crumbling or settle in the center of the Earth
The teacher said no, so that when he arrived to the center, the speed of his fall had reached a very large (8 km / s), which makes standing in that Anakthomra impossible, and this means that it will continue to fall to the bottom while reducing the speed to fall gradually until it reaches to the level of the corresponding edges of the well hole, and here we must cling to the edge of the well and strong, but fell a second time and sent back to the first hole
(And so will say that, who fell in the well fell into the highest for South hemisphere and will fall upon his return to the top for the north hemisphere)
This is confirmed by the laws of mechanics such as Newton's law of universal attraction and will take the process of falling back and forth 84 minutes 24 seconds exactly
Watermelon ... Bomb: - kinetic energy
Said the teacher can hold your hand Balrsash hum emanating heard someone said that the students this is beyond the scope of reasonable because the speed of the bullet high temperature and high
Actually happened to a French pilot was flying at an altitude of 2 km, where he saw something small moving close to his face what was it only that he found that he plucked a bullet taking off! But what is the interpretation that
Teacher said that the bullet does not remain always taking off speed Primary ranging between 800 and 900 m / s, as a result of air resistance reduces the bullet from its speed gradually and at the end of landing speed to 40 m / s only and with such speed was flying the plane at the time and this is what makes the shot look like a static for the pilot Vomcnh captured easily
This question I have for all Asraaaaahh I do not know where the sky
(I mean the sky the sky where there is a Lord Almighty)
Says in the hadeeth that the Prophet (peace be upon him) asked under way: Where God
She said, in the sky. He did not deny them that
Where is heaven?
Brothers sisters / if we say that the sky at the top, this is not true.
Because the highest in the Arctic is down to the south pole and the highest for the south pole is down for the Arctic and the highest for the equator is the horizontal direction for the North and South poles)
Where if the sky?
