320: Fill & Download for Free

The first untethered spacewalk was also the one with the greatest distance from the vehicle. On the twelth of February 1984, Astronaut Bruce McCandless took the MMU (Manned Maneuvering Unit) 320 feet (97 meters) from the Space Shuttle Orbiter Challenger (STS 41-B). Bruce holds the record for distance.Five astronauts flew the MMU: Bruce McCandless, Bob Stewart, Pinky Nelson, Joe Allen, and Dale Gardner. Here's a picture of Dale Gardner, on STS-51A using the MMU to capture a communications satellite and arrest its spin so that the Shuttle robotic arm could grapple it.

Anybody can score 330+ in GRE. I followed a 3 week preparation plan.It is important to understand that the GRE is very different as compared to the other exams we are used to giving, talking from an Indian’s perspective. Blind hard work will not serve any purpose and sometimes will be counterproductive.ETS (the company that conducts the GRE) wants to convince you that your score is a measure of how good you are at ‘critical thinking’, but in reality it is only a measure of how good you are at giving the GRE. So, fortunately for us, the more you practise in the correct way, the better you become at giving the GRE.The Correct Way (in my experience) :Quality > Quantity. Always. Please do not spend 10+ hours a day mechanically solving problems and forgetting about them as you move forward. This will cause you to plateau at a certain skill level. The key is small incremental improvements.For me, the ideal way was a simple 3 step process :1. Solve problems in small sets, around 20(+5 || -5) questions per set.2. Check your answers. See the solutions, understand them thoroughly.3. After checking all, recap the questions you got wrong, why, and what you learnt from them. This is extremely important.Let’s jump into the schedule now, shall we?Pre-prep phase (1 week) :Okay, I lied, it’s not really 3 weeks, but this pre-prep phase won’t take more than two hours of your time per day, and what’s more, you can easily do this while you eat or just before sleeping.What is to be done? Words, Words and more Words.Spend this week learning the words from the following apps :1. Barron’s 11002. Magoosh Flash Cards (around 1000 words)3. Manhattan Essential Words (around 500 words)Vocabulary is essential to understanding the Reading Comprehensions as well as the sentence completions, so please complete this before moving ahead!Week 1 :Congratulations! The boring part is done. This week, let’s do :1. 4 Practice Tests2. Practise each type of question in isolation. For example, do 20 Text Completions in one set. This will help you to identify weaknesses to work on.3. Brush up all the shortcuts and maths formulae that you encounter.(Online Magoosh article exists)Week 2 :This week, let’s move forward with :1. 6 Practice Tests.2. Do mixed practice sets now (All types of problems together), to simulate the actual GRE scenario.3. Strictly time your tests and practice sets. Keep 5 minutes per section as a buffer. Identify which type of questions you are slow at. Work on them.Week 3 :Buckle up, this is your final lap :1. 8 practice tests.2. Start reading AWA essays online, as well as general structuring tips. A lot of video material is available online. Practise a few essays if necessary.3. Revise the Vocabulary words and mathematical formulae.At the end of this schedule, you should be ready to face the GRE. So be confident, sleep well before the paper and ohh, don’t forget to carry a jacket. It’s freezing in there.Thanks for reading! Please do upvote if this helped you.

Well, a fighter pilot has to be really good at mathematics.Let me give you a few examples.You are flying at 22,000 feet, at 98 % R.P.M., with a ground speed of 320 mph with a course of 045.(Keep in mind that there is a huge difference between ground speed and relative air speed, due to factors such as direction and speed of wind. 045 means you are flying in the North East direction)Now, the Fighter Controller tells you to change course to 320, maintain a ground speed of 340 mph, and descend down to 15,000 feet within 2 minutes.Now, this is where the Mathematics comes in.From 22,000 to 15,000 feet in 2 minutes, i.e a descent of 7,000 feet in 2 minutes.Your Rate Of Descent should be 3,500/ minute.You have to turn towards the left in the process as well from 045 to 320. A course change of 085 towards the left.You will have a rate of turn of about 40–42 degrees/ minute.Now, you will also look at your RPM, and adjust it to get a ground speed of 340 mph.Now, ground speed is a function of Air Speed which is shown on your Air Speed Indicator and wind speed and direction.You need good knowledge of Vectors for the same.All these calculations, need to be real quick, and the actions should start the moment the controller has instructed you. There might be a target that is getting away on the course and at the height specified.If you take more than two minutes, he might get away.Fighter flying is not just spinning the aircraft the way you want to.It involves a lot of mathematics, physics and courage.The above example is probably the simplest of them all.Godspeed!
