Remember that question I asked in class why the existence of thunder as it is generated so great an uproar? Well, it is still existential doubt, and I stand by the hypothesis of separation of the air (just because it is incredibly cool), but I remember once talking to those "who know the song" mentioned something like
... the rays do not fall off, but that rise from it to the sky ...
Well, it turns out I bought a little camera and therefore did making the whole thing ... would be good to see that saying and see if we reach a conclusion about this, because the rays that out of the ground to the sky, it sounds like a movie. Here taken:
About the phenomenon of thunder, I conducted extensive research (read: I searched for a little while in wikipedia) and I found out that the hypothesis of air separation is not preposterous at all . is that when a beam passes through the air, heating it to do more than 28x10 ^ 3 ° C (36 ° C and is quite here in Killa) and this heat causes the air volume increases very rapidly expanding. But the air is cold at that point (hopefully here as well), and when the now warm air enters the air that I never fail to be cold, it contracts very rapidly, which leads to generate a phenomenon known as shock waves , which produces a sound with a high intensity, which is what makes her scream a lot (and many I must say) during an electrical storm.
What People Are Saying I hope reviews, especially the question of whether the rays that fall or rise to heaven "... and general comments about my first post (do not attack me pleaze U_U)
write their questions on the subject of the second set, if anyone knows the answer I could write and was taken into account as a bonus for the note of the second cut.
On a hot day before a rain, like these days, what do you think this factor influence on the air in general? Comments are invited until Monday 8 am to 8:00 pm. It is possible a bonus of 0.2 to those comments with some reason.

How to avoid being struck by lightning?
By LEONOR DE LA CRUZ
or.delacruz leon @ elheraldo.com.co
The October 23, 2002 lightning killed him the player Carepa Herman Gaviria of Antioquia com enzaba with their peers, the practice of Deportivo Cali, who was then leader of the soccer tournament mbiano colo.
15 days ago in Barranquilla, Jocelyn Cadavid, a 21 year old almost left paraplegic when receiving electrical urden desc by cell phone wearing under your clothes wet.
Every day falling on the earth one hundred rays per second, the damage they cause is not yet p ueden measure, but according to Colombia loses an estimated 100 million pesos per year from lightning, although not have this statistics on the number of deaths, although in the Serrania de San Lucas, near the municipality of El Bagre, Antioquia, has the highest activity global dial-ray.
Thomas
Rada, Ph.D. in Physics and professor at the University of North , said: "We have seen that lightning can destroy a person's life, it usually occurs because there is a high energy discharge, which is described by a difference po tential is generated, and the potential difference is created due to the pressures of the particles that make up air masses and other particles that form clouds. Usually it occurs on rainy days. "
explains that the flow of these masses and the charged particles na some way makes the clouds build up electrical charge and try to download through land because land is considered a sink or item that attracts all loads.
"When you create the potential difference between the cloud and the ground are looking to download through the air particles in the middle and that's where you appreciate what is commonly known as lightning, and it's really a shock to thousands of volts that presents " adds.
With regard to cell phones says that it does is create some kind of interference by a party. "When you have some electronic elements in some way such electronic devices are electrically conductive.
Between the possibility of lightning discharge in the head or shoulder, are more likely to be attracted by an electronic device.
Any metallic element mostly may be attractive to that sort of thing and a cell phone has metallic elements and draws electric shock.
Moreover, he says, when it builds a lightning rod for that essentially is the potential difference that travel through the metallic element to the ground and not go the other way.
best during a storm is to turn off mobile phones because their electromagnetic radiation can attract lightning.
Rada says the best place to take refuge in the open during a storm is in a closed car.
"Inside we shut the engine off the radio antenna and disconnect, close the windows and air intakes. While a lightning strike on the vehicle that will be charged only for the exterior while the interior will remain intact, just in case it's still better not come into contact with any metallic body, "he says.
100 Colombia pesos lost each year due to lightning, but there are no statistics on the number of deaths, although in the Serrania de San Lucas, near El Bagre, Antioquia, has the highest global lightning activity.
Recommendations physics Dr. Thomas Rada recommends:
* Withdraw all high place and refuge in low lying areas prone to flooding or not receive flood water.
* Do not run during a storm and less wet clothes, this is very dangerous. Create turbulence in the air and a convection zone that can attract lightning.
* Get rid of all cash and deposit material over 30 feet away. Rays take advantage of their good conduct.
* Never shelter under a tree or a rock or prominent elements alone. A lone tree by its moisture and vertical field intensity increases electric.
* Stay away from metal objects and items such as, fences, barbed wire, pipes, telephone lines and electrical installations.
* The recommended security position is placed still squatting, crouching as possible. This position will isolate enough because it does not excel much on the ground touching the ground only by shoes with material isolate us more.
Effects of lightning
The internist and neurologist says Jorge Daza Barriga receive a direct hit from lightning is almost synonymous with death, body and mostly to the brain are not prepared for burns it produces, the body suddenly rises by one degree in temperature and especially the brain is severely affected that change occurs immediately in addition to cardiac arrest and often also due to respiratory shock.
Are different effects that can cause people who are in a range of 120 meters of impact:
1. Skin burns.
2. Ruptured eardrum.
3. Lesions in the retina.
4. Fall to the ground by a blast.
5. Fall to the ground by muscular stiffness due to a slight step voltage.
6. Lung lesions and bone lesions.
7. Stress post-traumatic.
8. Death: cardiac arrest.
Respiratory arrest.
9. Brain injury.
If a person is struck by lightning:
* Electric shock does not stay in it, you can meet safely.
* The victim may have burns which was achieved by downloading and also for where it went, and in areas in contact with metal. You may also have damaged the nervous system, have lost sight and hearing and have broken bones.
* In any case request urgent medical assistance and not breathing or heart has stopped trying to revive her.
