Gravitational Waves




Just yesterday, scientists at The Laser Interferometer Gravitational Wave Observatory (LIGO) discovered something that will change our understanding of the skies forever. Gravitational waves formed by two black holes colliding with each other.

Albert Einstein theorized a century ago in 1916 that Gravitational waves existed. His theory was that is space time is the fabric of space, then huge events like two black holes banging into each other should send ripples through the fabric. These ripples were called Gravitational waves. But, since no one could prove that Gravitational waves existed, the theory was dismissed. That is, until the 1960's when an engineering professor called Joe Weber tried to prove that Gravitational waves existed. he did this by setting up two aluminum poles in vacuums. One in Maryland and the other in Chicago. He reasoned that is Gravitational waves passed through the earth, both the bars would ring like bells. People thought that Weber had proved that Gravitational waves existed but when other laboratories didn't get the same result, people started doubting this. Even so, Weber kept on trying until his death in 2000.

A professor called Reiner Weiss who is a co founder of LIGO was working at MIT when he was inspired to study Gravitational waves. He had a unique way to prove that Gravitational waves existed. He made a vacuum sealed L shaped tube with the two legs of equal size. There was a protrusion at the joint from where a laser was fired. A mirror divides the laser to go to both the leags. If there were no Gravitational waves, the lasers would have come back to the mirror at the same time. But, if there were Gravitational waves, the lasers would come back at slightly different times. The scientists used audio to check when the lasers came back so when a Gravitational wave passed through earth, they  heard a chirping sound.

Since the black hole collision happened billions of years ago, the waves weren't that big. The waves took this long to come to the earth because it was many light years away. According to Einstein's theory, the space time continuum would be distorted in places that were close to the place the two black holes collided. That is to say that time would have no meaning. Well this is still a theory and there is still no way to prove it. Anyway, let's just hope that Earth doesn't come close enough to any black holes

Will we be in for quieter plane rides?

The first jet engine, the turbojet, made by British engineer Frank Whittle, worked something like this. The thrust came from the air that was pushed into the front of the engine. Then, the air travelled into the compressor where it was squeezed, mixed with fuel, and ignited.  This causes the air, now very hot, to shoot out of the back of the engine, causing thrust.(The compressor was turned by a turbine that used exhaust gases to power itself.) But, these engines had a problem. They were not very fuel efficient and were very loud.




Next, came the turbofan engine, the engines that we use today. These engines worked similar to the turbojet engines. A fan, powered by the turbine, directed some air to move around the compressor instead of through it. Even though this air is not moving as fast as the exhaust gases, the sheer volume of it gives it more thrust than the turbojet. This made the engine more fuel efficient and quieter. Some of the latest and biggest turbofans engine fans are so big that they have a bypass ratio of 9:1. To explain this, we have to get into  little math. Let's say that we have ten parts of air. The 9:1 ratio means that only 1 part of the air is going inside the compressor while the other 9 parts are going around. This is much more efficient and provides a lot more thrust. These fans are getting bigger and bigger, but there is  a limit to which they can grow. As these fans get bigger, they also get faster and some fans are getting close to the speed of sound. If these fans reach the speed of sound, they will produce shock waves that cause dangerous vibrations. To slow down the fans but still keep the turbine running at an optimal speed, we need gearboxes. This is where the Purepower by Pratt and Whitney that is a geared turbofan engine comes in.



The fan will have a gearbox behind it and the engine will be bigger
Geared turbofans have been used in small jets for quite a few years. The reason they haven't been used in bigger jets is that since the engine is so big, the forces acting on the gearbox will be so high that it will break. Pratt and Whitney has been working on this problem for more than 15 years and spent more than $10 billion. But, all this work has paid off. Pratt and Whitney have created the new engine which is called the Purepower. They have a strong gearbox made out of nickel based alloys. This engine has a bypass ratio of 12:1 and is quieter and more fuel efficient. Even though this engine is going to be used by many planes, it has a few drawbacks. The engine will take quite a while to cool down. This may cause delays and in busy airports, take away a plane's take off shot.



It is too early to say whether the Purepower will be a success or not, but one thing is for sure. it will revolutionize the process of  engine manufacturing.

Boeing 787-9/10 vs Airbus A350XWB

The two largest plane manufacturers, Airbus and Boeing have always been trying to top each other in a war of innovations. Now, both companies have come out with two planes that will take flying to a whole new level. The Boeing 787-9 and the Airbus A350XWB. So which one is better?



Click for full image



The maiden flight of the A350XWB
Boeing Launched it's Dreamliner program in 2009 and have come out with 3 types since. The 787-8, 787-9 and the 787-10. These planes were Boeing's idea to reduce fuel consumption and were made out of Carbon Fiber and other composite materials. They were created to be a direct competitor of the Airbus A330. This pushed the European based Airbus to come up with another plane that could rival the 787. So, they came out with the A350XWB which, like the 787, was created to be a fuel efficient plane used for long haul flights. The A350XWB also has 3 models. The A350-800, the A350-900 and the A350-1000.


Range and Dimensions


The new Boeing 787-10 on which Boeing says it will start construction on in 2017 has a seating capacity of 330 with 2 class configuration. The Airbus A350 on the other hand has only 225 seats but with 3 class configuration. According to the Boeing and Airbus websites, the older Boeing 787-9 has a superior range of 7,635 nautical miles while the A350 has a range of 7,600 nmi. Boeing says that the new 787-10 will have a range up to 8,200 nmi but we don't know for sure yet. The Airbus 
A350-900 beats the Boeing 787-10 in all dimensions except length. here is a table that shows the dimensions of both planes. 



Note: The width of the 787 is smaller, but it has an option of having 8 or 9 seats in a row while the A350 has 9. 




Fuel Efficiency


Boeing claims that the 787-10 is 25% more fuel efficient than similar sized planes but Airbus claims the same for the A350XWB. Both planes are made out of carbon fiber and other composite materials that make the plane lighter and thus more fuel efficient. The planes also have new and fuel efficient engines. Boeing has been working with two engines for the Dreamliner. The Rolls-Royce Trent 1000 and the  General Electric while Airbus has only been working with one engine for the A350. The Rolls-Royce TrentXWB



Interior



Windows


The windows of a 787
The windows on the Dreamliner are one of the first things that catch the passengers' eyes. These windows are 70% bigger than older aircraft and 30% bigger than it's contemporaries. The A350's windows are bigger than other Airbus aircrafts' but noticeably smaller than the Dreamliner windows.

Another difference between the windows' is how they shut out light. Boeing has dimmable windows that can be dimmed or brightened again by pressing buttons. The A350, on the other hand has the classic shut out blind windows.

Lighting

The interior of a 787
Both Airbus and Boeing have gone above and beyond to provide the best LED lighting. Both the 787 and the A350 have millions of shades of lighting! The cabin, using the LED lighting, is programmed to look like the day sky with the sun in the day and the night sky with the moon and stars at night. This lets the passengers sleep and adjust to the time zone shift, thus reducing jet lag


Passenger Comfort



Both planes use stronger but lighter carbon-fiber fuselages that make the cabin more comfortable. The cabins will be pressurized to 6000 ft instead of the standard 8000 ft to make the passengers more comfortable. Both planes also use air filters and cycle out air every few minutes. 



The winner? Well, the person who gains the most is the passenger! The competition between Airbus and Boeing forces both companies to innovate and create a more comfortable experience for the passenger.

An Update On the Donald Trump Post

Donald Trump just recently said that he would have Muslims wear special IDs. He also said that we should demolish Mosques. This is crazy. He is doing the things Hitler did during World War 2. He forced Jews to wear yellow stars to identify them and burned down Jewish places of Worship. Donald Trump is doing the same thing to Muslims. he also said he would deport all Syrian refugees back to Syria. Even the Children! Is Donald Trump going to become the new Hitler? This is the question that everyone is asking!

Apple vs. Android

Apple vs. Android




Apple just came out with their newest innovations- IOS 9 and the iPhone 6S. These products have been wowing customers and the supply of the iPhone 6S has already been sold out. Many people think that iPhones are better, but the facts prove otherwise. In this post I am going to compare various features of Apple iPhones and Android phones and determine which is better.






1. Storage

When you buy an iPhone, your stuck with the amount of storage space the phone came with. But on the other hand, with an android phone, you can upgrade your storage whenever you want by inserting a Micro SD card.






2. Time Keeping 


Image result for samsung galaxy s6Android phones have special screen sensors that make the phone turn on automatically when you pull it out form your pocket. Android has daydreaming mode that lets you use you phone as a bedside clock without using too much power. Android alarms also tell you how many hours later your alarm will go off. This is good because you will know how much sleep you will get.




3. Customization


Android phones let you put widgets that do various things on your home screen. iPhones force you to keep all your apps on your home screen, but android lets you keep apps of your choice on the home screen while the 
rest go into the my apps page.



                                                          4. Photos

Android's video and photo quality is way better then apple's. Google photos also offers free unlimited storage linked to your e-mail account.


5.Keyboard

The android keyboard is way better. It shows punctuation and numbers on the same page as letters. Apple just recently started showing lowercase letters on their keyboard and they copied the swipe feature from android.

                                                                                                                                                                                                                                                                         






6. Notifications

On android, you can see what notifications you have without swiping down. This helps you know if the notification in worth looking at or not. Apple doesn't have this feature.



7. Apps and Music

Image result for app store vs google playOn android, you can download music and apps from the internet. On apple, you have to use the app store or i tunes to do download apps or music. There are also more apps on Google Play than the app store and they tend to be cheaper.




8. Maps

Everyone knows that Google Maps is way better than apple maps. Also, when using Siri to ask for directions, your iPhone will bring up apple maps. There is no option to change it to apple maps.












All these facts prove that android is better than apple and I hope this helped you choose between the two of them!
