Can you calculate how far away lightning struck by how long it takes for the thunder to arrive?




hi all,

It would be great if we calculate how far away lightning struck by how long it takes for the thunder to arrive...isnt it?

Sound travels through air at "the speed of sound." Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second.
As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.

When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck. If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away. :)

See you all with another excellent topic!!!

Can I get struck by lightning when I'm indoors?

Hi all,

This is most interesting as well as important article...

Over 1,000 people get struck by lightning every year in the World,and over 100 of them die as a result of the strike. Lightning is a very dangerous force that, yes, can even reach you indoors if you're in contact with the telephone or plumbing.

If lightning strikes the phone line outside your house, the strike will travel to every phone on the line -- and potentially to you if you are holding the phone. So, if you are indoors during a lightning storm, stay off the phone. If you must call someone, use a cordless or cell phone -- that way, you're not in contact with any wires that run outdoors.

Stay away from plumbing pipes like your bath tub or shower, as well. Lightning has the ability to strike a house or near a house and impart an electrical charge to the metal pipes used for plumbing. If you're touching those pipes or anything connected to those pipes, that electrical charge has a path to you. This threat is not as great as it used to be, because PVC (polyvinyl chloride) is often used for indoor plumbing these days. If you are not sure what your pipes are made of, wait it out.

And while you're at it, switch off your appliances and electronics before the storm hits. Such devices as your computer, television and air conditioner all provide potential pathways between the lightning and you.

So be very careful during the lighting even if you stay indoors!

What do you call the @ symbol used in e-mail addresses?

Hi all,

The funny little a with its tail circling back around it is probably one of the most commonly used symbols today. So it is truly amazing to learn that there is no official, universal name for it. The most accepted term, even in many other languages, is to call it the at sign. But there are dozens of different words used to describe it. A lot of languages use words that associate the shape of the symbol with some type of animal.

Here are a few examples of the many exotic terms associated with the @ symbol:

apestaart - Dutch for "monkey's tail"
snabel - Danish for "elephant's trunk"
kissanhnta - Finnish for "cat's tail"
klammeraffe - German for "hanging monkey"
kukac - Hungarian for "worm"
dalphaengi - Korean for "snail"
grisehale - Norwegian for "pig's tail"
sobachka - Russian for "little dog"

Before it became the standard symbol for e-mail, the @ symbol was typically used to indicate the cost or weight of something. For example, if you bought five oranges for $1.25 each, you might write it as 5 oranges @ $1.25 ea. It is still used in this manner on a variety of forms and invoices around the world.

The actual origin of the symbol is uncertain. It was used by monks making copies of books before the invention of the printing press. Since every word had to be painstakingly transcribed by hand for each copy of a book, the monks that performed the copying duties looked for ways to reduce the number of individual strokes per word for common words. So, the word at became a single stroke of the pen as @ instead of three strokes. While it doesn't seem like much today, it made a huge difference to the men who spent their lives copying manuscripts!

Another origin tale states that the @ symbol was used as an abbreviation for the word amphora, which was the unit of measurement used to determine the amount held by the large terra cotta jars that were used to ship grain, spices and wine. Giorgio Stabile, an Italian scholar, discovered this use of the @ symbol in a letter written in 1536 by a Florentine trader named Francesco Lapi. It seems likely that some industrious trader saw the @ symbol in a book transcribed by monks using the symbol and appropriated it for use as the amphora abbreviation. This would also explain why it became common to use the symbol in relation to quantities of something.

How much power does a small transformer consume if it is plugged in but not doing anything?

Hi all,

I hope everyone would be aware of the term TRANSFORMER... anyways, will give you a brief idea about the term...

I could tell you the plenty of operations which the transformer does, among them its mainly used to convert a AC Current to minimal DC voltage. Most transformer cubes that you find around the house produce a low-voltage DC current (3 to 12 volts, and less than an amp of current). DC current is necessary because rechargeable batteries store DC current, because most electronics require low-voltage DC current and because small DC motors run directly from batteries and are the least expensive motors available.

Hope this information is enough!! We shall discuss our topic in detail now,

As said, transformers have been used by various devices,lets say for ex: printer, scanners,speakers, answering machine, cordless phone, electric screwdriver, electric drill uses Transformer as a source for them...

Do you know, by just connecting a transformer to the AC switch would consume power...
It would consume more power if its connected to other devices during charging of materials. If you have ever felt one and it was warm, that is wasted energy turned to heat. The power consumption is not large -- on the order of 1 to 5 watts per transformer. But it does add up. Let's say that you have 10 of them, and they consume 5 watts each. That means that 50 watts are being wasted constantly. If a kilowatt-hour costs a dime in your area, that means you are spending a dime every 20 hours.

Hope you have STABILIZERS connected either with TV or Fridge, isnt it?

Wait... You may think why do i ask the above stupid question, isnt it ? :)

Hmmm! my question would make sense... read below,

Nowdays, people have forgotten the habit of Switching OFF the TV properly from the MAIN SWITCH. Have you seen these cases? The TV LED will be in RED eventhough the screen is blank, in this case, the TRANSFORMER utilizes the power for charging the circuits, since its connected with AC power directly... the end result, your METER BOX will be running like a black HORSE! :)

I would suggest you, do SWITCH off the appliances which you use TRANSFORMERS as a source,Stabilizer is a real time example for it... so... lets not forget the STABILIZER case... ;)

If you dont agree with my points, pl tell this buzzword along with me,

" I am ready to give my half of the salary to the ELECTIRICITY dept" ... :) ha ha!


Hope you are clear with the confusion we had been from a long time...

Will meet you with another nice topic!

who ll take care of our poor people, if we ignore them?

Hi all,

Chain of questions for you this time, will you answer?

Would you help the people who are starving?
Would you help the people who stay in the unhygenic environment?
Would you help the people who are financially backwards?

If you agree with the above chain, you wouldnt feel hard to read the below one,

Would you help the TEAM or Organisation who does the humanitarian help for the poors?

Well, who does this outstanding service??

Bharat Sevashram Sangha (BSS), it is a spiritual brotherhood of monks and selfless workers devoted to the service of humanity, a philanthropic and charitable organization with non-sectarian , non-communal and non-political character and outlook.

The main objective of the current project is to support the humanitarian activities of Bharat Sevashram Sangha (BSS), Barajuri. The various activities of BSS are suffering acute financial crisis and that is hampering their positive efforts towards the well-being of the Backward classes of the surrounding area.

Unisys procures a £14.7m contract from US Army !

Hi all,

Unisys, a worldwide technology services and solutions company, has procured a healthy contract from the US Department of Defence (DoD) is worth around £14.7m. Unisys began working with the DoD on RFID technology 13 years ago, to maintain and enhance an in-transit visibility system for supplies using RFID.

Unisys, an industry leader in the integration, deployment and support of automatic identification technology, and the U.S. Army have worked tirelessly to establish, develop, operate and maintain one of the largest, most successful RFID networks in the world.

Wait a minute, what is an RFID and whats the use of it??

This must be your question, if you havent heard of this technical name....isnt it?

Here comes the much awaited answer.., ;)

Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio frequency (RF) signal and perhaps other specialized functions. The second is an antenna for receiving and transmitting the signal. An emerging technology called chipless RFID allows for discrete identification of tags without an integrated circuit, thereby allowing tags to be printed directly onto assets at lower cost than traditional tags. They are widely used in the hospitals,defense or even used to track a particular object...

Ok... In what way RFID enables the Military operations??

Unisys tracks approximately 125,000 shipments of supplies each week, including ammunition, food/rations and water, medical supplies, vehicles, vehicle parts and aircraft. Attached to these shipments are RFID tags that store information vital to the soldier.

Unisys tracks shipments across all modes of transportation - truck, rail, ship and air - to their final destinations in combatant commands worldwide.

Fixed and handheld readers send and receive radio signals to and from the tags. Because data written to each tag are replicated among five servers, users worldwide have access to the same information on each item. Consequently, decision-makers at all levels of command and throughout the logistics supply chain can plan, prioritize and redirect shipments accordingly and collaboratively.


Lets not to dig this topic more deeply as it may eat our golden years... :)

See you all with another interesting topic soon...

Best Regards!

RFID's @ Heathrow Airport soon!

Hi all,

RFID[Radio Frequency Identification] tags will be soon installed at the heathrow airport terminal 5, in order to monitor the Taxi exists to handle a predicted one million taxi movements when the 2012 Olympics begin.

The system will reduce taxi waiting times at what will be the world’s busiest airport and allow it control and track taxi access to the terminals. Fixed and handheld devices will monitor taxis, which will be equipped with RFID tags, to identify vehicles and their drivers. Data will then be transmitted back to system headquarters over a wireless network. Staff will also be able to communicate using the devices to ensure flexibility in the event of unplanned events like road works or accidents.

Hope u enjoyed it...

Will meet u all with another amazing topic... :)

US Scientists demonstrate wirless technology!

Hi all,


US Scientists have once again made an amazing job recently. Yes, they have developed a way to made it easier to power the other device wirelessly,by solidly testing an electric bulb.

The experiment set up goes in this way...

They have taken two 60 cm copper coils with an source(transmitter),which is attached to a power supply and the destination(receiver), placed 7 ft away to a light bulb.

The discovered technology could charge a 60W light bulb from a distance of 2m (7ft), which it could also be used to charge a LAPTOP in future, just to patch up the low battery problem which we many of us face nowdays... :)

It would be better if we could get better power from the source wirelessly, would be a way to solve plenty of issues in the daily life... Isnt it ?!!

India in trillion-dollar economy club!!!

Our Country has retained the 12th spot by joining the Trillion dollar economy club,by significant growth in the manufacturing sectors.

Rupee's value has been consistently improved in the global market against the Dollar value. This would be one of the true reasons for procuring this spot, i reckon.

Pl have a look at the article,

http://www.ibnlive.com/news/business/05_2007/india-is-trilliondollar-economy-41800.html

If this stage continues, i will promise you, the dollar value may not amplify further in mere future, which may decline to some near value around 35 in a short time.

lets keep our fingers crossed for this special day :)

Microsoft has introduced Surface Computer!

Hello all,

Microsoft has finally introduced the Surface Computer in the market,chariman Bill Gates unveiled.

The 30-inch display screen is mounted under a plastic tabletop and will initially cost $5,000 to $10,000. It will, at first, only be available in select hotels, casinos, and T-Mobile stores in November.

This will going to be one of the most favorite products in the forthcoming years, but unfortunately the cost is little higher,which the middle class peopl have to sell their house! lol :)
