Unveiling the F1 enigma series.
Formula one or F-1 is one of the most prestigious and technologically advanced sports in the world.The never-ending battle for supremacy makes F-1 one of the most competitive, expensive and demanding sports in the world.
It is a game of chess played at 300 Kmph.The real war though is fought behind closed doors in the secrecy of the team’s headquarters.
As March 13 marks the start of a new season of this motor sport, we decided that it was high time we unveil the technology that underlies the stardom of the automobile industry - The formula one car.
From questions like what enables a formula one car to go upside down a tunnel? to awfully simple questions like does the F-1 car have an ignition key and why not? we will try to cover it all. Most importantly, we will try to weave what you already know to explain new concepts.
The rough list of contents for this series are:
A brief history of Formula one.
Aerodynamics- The art of glueing the car to the ground.
The nucleus of the car- F-1 engine and the gearbox.
One has to stop!! -Brakes and steering wheel.
Tyre and fuel technology- This rarely is given the importance that it needs.
Fun facts and trivia with every post.
If you have any questions that you have in mind to be answered and topics that we have missed, please post it in the comments section below. We would be delighted to address them.
Hang onto your hats, it’s going to be a wild and crazy ride ahead!
तुम धन्य हो वर्षा रानी, मृत्प्रायों को देती पानी जग में तुम खुशहाली लाती, खेतों में हरियाली लाती………… संग अनेक सहेली लाती, तपते जग में शीतलता लाती नए-नए तुम फूल खिलाती, जंगल में भी मंगल लाती………… तुम जग की रक्षा करती, तुम बिन कौन हमें दे पानी अन्नदात्री है तू ही रानी, तुम धन्य हो वर्षा रानी………… जब तुम कृपा करती हो रानी, जग में भर जाता है पानी तुम पर हीं अरमान हमारा, तुम पर हीं है प्राण हमारा………… बस इसलिए तो हम तेरी करते हैं आगवानी, चाहे राजा हो या रानी सब मर जाएँ बिन पानी, पशु हों, पक्षी या मानव सबका हीं जीवन है पानी………… तुम जब जाती हो रानी, तो रो पड़ते हैं सब प्राणी यह सत्य है करुण कहानी, तुम यहीं रहो मनमानी………… तब हम भी सुखी रहेंगे, नव जीवन प्राप्त करेंगे तुम धन्य हो वर्षा रानी, मृत्प्रायों को देती पानी…………
In India since the stone age there were no existence of apartheid here. It came after the effect of mughal empire in India and after that British came and started a devide and rule game here. They mainly stroked on religion diversity and customs in Indian society. #Padmavati

When Dead Stars Collide!
Gravity has been making waves - literally. Earlier this month, the Nobel Prize in Physics was awarded for the first direct detection of gravitational waves two years ago. But astronomers just announced another huge advance in the field of gravitational waves - for the first time, we’ve observed light and gravitational waves from the same source.
There was a pair of orbiting neutron stars in a galaxy (called NGC 4993). Neutron stars are the crushed leftover cores of massive stars (stars more than 8 times the mass of our sun) that long ago exploded as supernovas. There are many such pairs of binaries in this galaxy, and in all the galaxies we can see, but something special was about to happen to this particular pair.
Each time these neutron stars orbited, they would lose a teeny bit of gravitational energy to gravitational waves. Gravitational waves are disturbances in space-time - the very fabric of the universe - that travel at the speed of light. The waves are emitted by any mass that is changing speed or direction, like this pair of orbiting neutron stars. However, the gravitational waves are very faint unless the neutron stars are very close and orbiting around each other very fast.
As luck would have it, the teeny energy loss caused the two neutron stars to get a teeny bit closer to each other and orbit a teeny bit faster. After hundreds of millions of years, all those teeny bits added up, and the neutron stars were *very* close. So close that … BOOM! … they collided. And we witnessed it on Earth on August 17, 2017.

A couple of very cool things happened in that collision - and we expect they happen in all such neutron star collisions. Just before the neutron stars collided, the gravitational waves were strong enough and at just the right frequency that the National Science Foundation (NSF)’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and European Gravitational Observatory’s Virgo could detect them. Just after the collision, those waves quickly faded out because there are no longer two things orbiting around each other!
LIGO is a ground-based detector waiting for gravitational waves to pass through its facilities on Earth. When it is active, it can detect them from almost anywhere in space.
The other thing that happened was what we call a gamma-ray burst. When they get very close, the neutron stars break apart and create a spectacular, but short, explosion. For a couple of seconds, our Fermi Gamma-ray Telescope saw gamma-rays from that explosion. Fermi’s Gamma-ray Burst Monitor is one of our eyes on the sky, looking out for such bursts of gamma-rays that scientists want to catch as soon as they’re happening.
And those gamma-rays came just 1.7 seconds after the gravitational wave signal. The galaxy this occurred in is 130 million light-years away, so the light and gravitational waves were traveling for 130 million years before we detected them.
After that initial burst of gamma-rays, the debris from the explosion continued to glow, fading as it expanded outward. Our Swift, Hubble, Chandra and Spitzer telescopes, along with a number of ground-based observers, were poised to look at this afterglow from the explosion in ultraviolet, optical, X-ray and infrared light. Such coordination between satellites is something that we’ve been doing with our international partners for decades, so we catch events like this one as quickly as possible and in as many wavelengths as possible.
Astronomers have thought that neutron star mergers were the cause of one type of gamma-ray burst - a short gamma-ray burst, like the one they observed on August 17. It wasn’t until we could combine the data from our satellites with the information from LIGO/Virgo that we could confirm this directly.
This event begins a new chapter in astronomy. For centuries, light was the only way we could learn about our universe. Now, we’ve opened up a whole new window into the study of neutron stars and black holes. This means we can see things we could not detect before.
The first LIGO detection was of a pair of merging black holes. Mergers like that may be happening as often as once a month across the universe, but they do not produce much light because there’s little to nothing left around the black hole to emit light. In that case, gravitational waves were the only way to detect the merger.

The neutron star merger, though, has plenty of material to emit light. By combining different kinds of light with gravitational waves, we are learning how matter behaves in the most extreme environments. We are learning more about how the gravitational wave information fits with what we already know from light - and in the process we’re solving some long-standing mysteries!
