Necessary to take precautions while using flash light
With deep pains (and tears in my eyes), i am sorry to inform You that yesterday morning, one of my dear friend's elder son (Mr. Aditya Suresh Joshi), age 19, studying in 1st year of engineering, died in Keshvani Hospital, Mumbai. He was admitted in Keshavani Hospital as burned patient.
4 days back this boy had gone to Amravati (One of the district place located in State of Maharashtra) on study tour. After their study was over, he, his classmates & his teachers, all of them were standing on "Badnera" railway station to catch the train. "Badnera" is the name of the railway station for "Amravati" city.
As soon as they arrived on Badnera Railway station, many of them started taking pictures of their friends using "Mobile Phones" and/or "Digital Camera". One of them complained that, in his camera, he was not able to capture more number of friends in one frame. He was not able to catch the angle. Another boy suggested that let's climb on train boogie and take picture so that all of them can be accommodated in single frame.
At that there was one goods wagon (all of them were oil tankers) train resting between 2 main railway lines.
Kumar Aditya climbed up oil boogie. Above his head, 40,000 volts electrical line was passing through. As soon as he clicked the digital camera? 40,000 volt current passed through the camera flash light to his camera and then from his camera to his fingers and then from his fingers to his body. All this happened within fraction of minutes. Next moment he was thrown from the top. His body was half burned on the spot.
At that time, his father (my friend) was traveling in Bangkok. His many friends in Pune came to know about this via mobile SMS. They instantly arranged air ambulance in Amravati and his burned body was brought to Keshavani Hospital, Mumbai. i was told that this is the best hospital in Mumbai. For 1 and 1/2 day or so he was talking to his relatives. When he was admitted to the hospital, at that time only, doctor informed his relatives that don't keep great hopes. Because of lot of complex issues in half burned body? He died yesterday morning.
·Now how many of us are aware about this technological threats & dangers? Honestly, Kumar Aditya and his father was not aware. His family was not aware. Our entire friend circle of more than 12,000, we were not aware. Now should we call ourselves as fully educated and fully knowledgeable people? Please Think of it.
·Please avoid mobile phones on petrol outlets,
·Please avoid talking on mobile phones while driving. i also know many of my friends who do not bother about this good suggestion and each one of them have opted for "Chalta Hai Yaar Attitude".
·Please avoid talking on mobile phones while they are in charging mode.
·Please avoid charging mobile phones near Your bed and/or near wooden furniture. Avoid mobile phones near high voltage electrical lines like railway stations and use flash lights.
·My friend, his family members and we all friends learned our lesson with loss of young life. Now Would You like to empower Your friends about this accident so as to avoid future accidents? We can save human life by empowering all the IT users who are in Your network?
Please Please.....I request you to send this very important life threatening information to your loved ones.....
During my course of teaching of elasticity ,i teach about the energy stored in the stretch string.One of the example is a sling in which when rubber string is stretched elasticpotential energy get stored and when it is released it converts into kinetic energy. WORK DONE AND ELASTIC ENERGY Let us take the example of a wire. Suppose the original length of the wire is L, When not deformed, there are no internal forces. As the length of the wire increase from L to L + DL, internal forces increase from 0 to F. Suppose at any instant when the length is (L +x), the internal force is Fx. The work done to further increase the length through dx is Fxdx, hence total work done
W=Fxdx =EA/L x dxSo the total work done is W = ½ EA/L (DL)2W = ½ F (DL)Thus, the elastic energy per unit volume is given by-U = W/AL = ½ stress ´ strain(1)The above results is true for all types of stress and strain.(2)The work done per unit volume or the elastic energy per unit volume is given by half the product of stress an…

Refrigeration: the process of decreasing the temperature of some thing (my definition). Air conditioning (AC) can be a form of refrigeration.
There are several ways to reduce the temperature of things – like a person or a beer. The history and physics of cooling things can be quite interesting. I’m not a historian, so I am only going to speculate on the timeline of events in the life of refrigeration. However, I feel comfortable explaining the physics in each method.
Humans Discover Sweat
Humans just can’t help it. Sometimes they get hot. But alas! Humans have a built in cooling systems. It’s called sweat. In order to understand how it works, maybe we should first look at temperature. You can measure the temperature in Celsius (°C) or Fahrenheit (°F), but what are you actually measuring?
If I were to give a simple definition of temperature, I would say that it is a measure of the average motion energy of the particles that make up that object. T…
Yesterday i found this interesting problem . Have fun in doing this.
On April 15 an airplane takes off at 4 : 40 p.m from Belem. Brazil bound
for Villamil, Ecuador (in the Galapagos). The plane lands at 8 : 40 p.m.
Villamil local time. The sun sets at 6 : 15 p.m. in Belem (local time), and 7 :
06 p.m. in Villamil (local time). At what time during the flight do the
airplane passengers see the sun set?
