Today 101st Anniversary of the First Electric Traffic Signal System 

The world’s first electric traffic signal is put into place on the corner of Euclid Avenue and East 105th Street in Cleveland, Ohio, on this day in 1914.

In the earliest days of the automobile, navigating America’s roads was a chaotic experience, with pedestrians, bicycles, horses and streetcars all competing with motor vehicles for right of way. The problem was alleviated somewhat with the gradual disappearance of horse-drawn carriages, but even before World War I it had become clear that a system of regulations was necessary to keep traffic moving and reduce the number of accidents on the roads. As Christopher Finch writes in his “Highways to Heaven: The AUTO Biography of America” (1992), the first traffic island was put into use in San Francisco, California in 1907; left-hand drive became standard in American cars in 1908; the first center painted dividing line appeared in 1911, in Michigan; and the first “No Left Turn” sign would debut in Buffalo, New York, in 1916.

Various competing claims exist as to who was responsible for the world’s first traffic signal. A device installed in London in 1868 featured two semaphore arms that extended horizontally to signal “stop” and at a 45-degree angle to signal “caution.” In 1912, a Salt Lake City, Utah, police officer named Lester Wire mounted a handmade wooden box with colored red and green lights on a pole, with the wires attached to overhead trolley and light wires. Most prominently, the inventor Garrett Morgan has been given credit for having invented the traffic signal based on his T-shaped design, patented in 1923 and later reportedly sold to General Electric.

Despite Morgan’s greater visibility, the system installed in Cleveland on August 5, 1914, is widely regarded as the first electric traffic signal. Based on a design by James Hoge, who received U.S. patent 1,251,666 for his “Municipal Traffic Control System” in 1918, it consisted of four pairs of red and green lights that served as stop-go indicators, each mounted on a corner post. Wired to a manually operated switch inside a control booth, the system was configured so that conflicting signals were impossible. According to an article in The Motorist, published by the Cleveland Automobile Club in August 1914: “This system is, perhaps, destined to revolutionize the handling of traffic in congested city streets and should be seriously considered by traffic committees for general adoption.”

       President Abdul Kalam dies in Shillong

Shillong: former president apj abdul kalam,the 'missile man' who came to be known as 'people's president' died on monday after he collapsed during a lecture at the IIM in shillong on monday evening

                                          kalam who woul have turned 84 in october,was confirmed dead more than two hours after he was heeled in to the ICU of Bethany hospital in a critical condition following the collapse at around  6.30 pm.

                                       According to reports,kalam suffered a massive cardiac arrest during the lecture at IIM,Shillong.

                                     Considered the most popular president,kalam became the 11th head of the state and occupied the post between 2002 and 2007 but lack of consensus denied a second term in office for a man who came from out side political spectrum.


                                   Meghalaya Governor V Shanmughanathan,eho rushed to the hospital on hearing the news of his admission,said kalam died at 7.45 pm.despite medical team best efforts,he could not be revived.


chief secretary PBO warjiri told reporters  out side the hospital that he had spoken to Union Home Secretary LC Goyal asking for necessary arrangements  to be made for carrying kalam's body from Guwahathi to Delhi on tuesday morning.

"The former president has been admitted to Bethany hospital in a critical condition ,"M.Kharkrang,sp.Khasi Hills said earlier.

Doctors from the army hospital and North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences(NEIGRIHMS) rushed to Bethany hospital but their efforts proved to be of no avail.

 A seven-day national mourning will be declared by the Centre, Union Home Secretary LC Goyal said. Both the Houses of Parliament are likely to make obituary references and adjourn as a mark of respect to his memory.
Avul Pakir Jainulabdeen Abdul Kalam rose from humble origins to become the President in the most unexpected manner during the NDA government under Atal Bihari Vajpayee after an all party consensus minus the left parties that saw him through in an election which he won handsomely.

An aeronautics engineer from Madras Institute of Technology, Kalam was considered the brain of missile programme in India got and as Chief Scientific Adviser to Vajpayee was also instrumental in the Pokhran nuclear test in 1998.

As President, Kalam utilised any opportunity that came to him to address students, especially school children, to dream big so that they became achievers in life. A bachelor, the former President was a veena player and was deeply interested in Carnatic music.

He was vegetarian all his life.
Earlier during the day, Kalam had tweeted about his function at IIM Shillong.

He is inspiration for many young stars.Now he is not with us but his thoughts and memories will live ever in our hearts.

The Webcam Pulse Detector Shows Your Life Signs Using Your PC's Camera

Windows/OS X: Your computer's webcam can be useful for more than just quick photos and video calls. The Webcam Pulse Detector is a fun, open source application originally designed at NASA to use your connected camera to take your heart rate. Now you can try it out at home.

                                                        The utility is simple to use. Just grab the executable and run it. It's a self-contained python application, so it shouldn't need any dependencies or other files to work. Once you open it, you'll get a view of your camera, and it'll ask you to guide your face into view so it can get a fix on your face and your forehead. Once it's in the right position, press S to lock your face, and watch the app take its readings. You'll even get a little graph (if you press D) that shows your heart rate over the time you've had the app open.

                                                     To be fair, it's not perfect at all. My readings tended to be particularly low (maybe it has more difficulty with people of darker complexion) but for others it seemed to work pretty well. The Webcam Pulse Detector is available for OS X and Windows in pre-compiled binaries, and a version for Linux is on the way soon. You can check out the project homepage (and download it to try yourself) below.

Nepal earthquake, magnitude 7.3, strikes near Everest

A major earthquake has struck eastern Nepal, near Mount Everest, two weeks after more than 8,000 died in a devastating quake.

At least 29 people have been killed and 1,006 injured, according to the Nepali government.

The latest earthquake hit near the town of Namche Bazaar, near Mount Everest.

The US Geological Survey said it had a magnitude of 7.3. An earthquake on 25 April, centred in western Nepal, had a magnitude of 7.8.

The latest tremor was also felt in northern India and Bangladesh, and was centred east of the Nepalese capital Kathmandu, in a rural area close to the Chinese border.

Read eyewitnesses' account of the earthquake

In Kathmandu, which was badly damaged last month, people rushed out of buildings as the quake struck at 12:35 local time (06:50 GMT).

Rescue helicopters have been sent to districts north-east of the capital, that are believed to be worst hit.

A spokesman for Nepal's government told the BBC that 31 of the country's 75 districts had been affected.

You could feel it really strongly. It went on for about 25 seconds - the ground was shaking, the birds started squawking, you could feel the buildings shaking.

There was another aftershock and people were all out on the street. That aftershock really added anxiety and panic. People started crying.

They are calm but you can tell they are all scared.

The BBC's Yogita Limaye, who was in Nepal's mountains when the latest earthquake struck, said: "The earth shook and it shook for a pretty long time.

"I can completely understand the sense of panic. We have been seeing tremors: it's been two-and-a-half weeks since the first quake. But this one really felt like it went on for a really long time. People have been terrified."

The quake was followed by another strong aftershock, measuring 6.3

The earthquake caused some buildings to collapse in the centre of Kathmandu

At least four people were killed in the town of Chautara, east of Kathmandu, where a number of buildings are reported to have collapsed.

The International Organisation for Migration said bodies were being pulled from rubble there.

Krishna Gyawali, the chief district officer for Chautara, said there had been a number of landslides.

The quake struck at a depth of 15km (9.3 miles), according to the US Geological Survey - the same depth as the April 25 quake. Shallow earthquakes are more likely to cause more damage at the surface.

Tuesday's earthquake is likely to be one of the largest to hit Nepal, which has suffered hundreds of aftershocks since 25 April.

The 7.3 quake was followed by six aftershocks of magnitude 5.0 or higher.

One tremor that hit 30 minutes later, centred on the district of Ramechhap, east of Kathmandu, had a magnitude of 6.3.Jump media player

Analysis: Jonathan Amos, science correspondent, BBC News

Scientists are already producing some preliminary analyses of Tuesday's quake.

The epicentre this time is about 80km (50 miles) east-north-east of Kathmandu, halfway to Everest. On 25 April, the big quake began 80km to the north-west of the capital.

In April, we saw the fault boundary rupture eastwards for 150km (93 miles). And the immediate assessment suggests Tuesday's tremor has occurred right at the eastern edge of this failure.

In that context, this second earthquake was almost certainly triggered by the stress changes caused by the first one. Indeed, the US Geological Survey had a forecast for an aftershock in this general area.

Its modelling suggested there was 1-in-200 chance of a M7-7.8 event occurring this week. So, not highly probable, but certainly possible.

Quake experts often talk about "seismic gaps", which refer to segments of faults that are, to some extent, overdue a quake. Tuesday's big tremor may well have filled a hole between what we saw on 25 April and some historic events - such as those in 1934, that occurred further still to the east.

6 Habits That Kill Your Intelligence

 

Although you may not believe it, there are certain habits that you have fallen in to, which are hindering your ability to move forward in life. Although you think it has no effect on your life, these bad habits that kill your intelligence not only set you back, they are also going to stop you from being able to accomplish certain things, or attain the goals that you have set for yourself. These are some habits that are holding you back, and possibly causing you to make poor choices or decisions in your life.

1. Not Creating and evaluating

It is impossible for you to go forward and backward at the same time; it is also impossible for you to go up and down simultaneously, the same goes with your mind. When you are trying to create something, and evaluate the success at the same time, you are never going to get a project going.

You first have to find out what you want to create, how it is going to work, and draw out the plans; you will then create a project or product, and only after it has been created and implemented, can you begin to evaluate how it is performing, in any situation. Give things time, and do not try to do two complete opposite tasks, at the same time.

2. You think you’re are expert 

The expert syndrome is another habit people have, which kills their intelligence. When you believe you are an expert at every and anything, you stop learning. You will never be humble enough to listen to others, and learn from their experience.

This is in fact going to set you back, and is going to hinder your intelligence. Be open to the fact that you do not know everything, and that anyone can help you learn something new. Not only will this allow you to learn new things, it will help you come off as less of an ignorant person with others.

3. Fear -

If you are always afraid you are going to fail, you are never going to try something new. It is likely you are going to fail, more than once, especially if you have never done something before. But, if you never try, or never attempt to learn something new because you are afraid you are going to fail, you are never going to get better, and are never going to learn new things. So, you have to eliminate the fear, and accept the fact that failure comes with everything new you are going to try.

4. Lack of confidence -

This goes hand in hand with the fear to fail. If you always believe you are going to mess up, and do not have confidence in the things you do, you can never learn and grow. Having confidence in yourself, even if you are doing something wrong, allows you to learn, and grow, and it allows you to move forward. This will help build intelligence, and allow you to learn new things, and experience new things in life.

 5. Creating limits -

Although you may have certain limits (such as financial, or certain capacities), when you create false limits, you are hindering your intelligence and ability to learn. When you put obstacles in the way, that are not really there, you are never going to try things. This will not only kill your intelligence, it will also stop you from trying new things, and learning new things that can make you better, and can possibly make you a more successful person. So, remove irrelevant limits, and those which are only created by you in your mind.

6. Drinking -

Although it is something enjoyable, alcohol does hinder your intelligence and ability to comprehend or grasp subjects. So, drinking every once in a while will not kill all brain cells, but you should know that alcohol (and drugs), will hinder, and kill your brain cells, making it harder to learn new things. So, if you do consume alcohol, it should be done lightly, and it should be done infrequently, so as to ensure you are not going to cause damage to your brain, and possibly cause problems with the future ability to learn new things and expand on knowledge basis.
