Guten Tag to my readers who may or may not exist.
My blog would seem rather dead if I didn’t update it. Thus I am compelled to update to show, I am currently alive and not dying for mysterious reason( exams).
It is Week 12 for people not in Uni Melb, a.k.a. the last week of the semester. And it also signifies that exams is a mere two weeks away. However, let me not dampen your mood by recounting the horror stories of physics and mathematics.
Last week, for our final assignment for engineering, we had to run a Lego Mindstorm Robot through a course. It had to complete the course under 30 seconds to get full marks.
Thats right. Its a race where the robot destroys competitors and race to the end.

But alas, the university has an ethic policy which forbids violence so we have to downgrade our ultimate-scorpion-killer-robot to this harmless looking one.
Despite developing a flawless program for the robot, it simply would not follow instructions but prefer to do the robot dance, the jump around senselessly dance .
Yeap. Something similar to the above picture but not as cool. After a thorough investigation and despite the help of 2 tutors (they have masters in engineering mind you), the problem could not be detected. It was not until late in the workshop that the problem was discovered to be a stuck wheel. Once the wheel was unstuck, the robot was invincible. Cruising a neck breaking speed of 2cm a second, it finished the course in an awesome lap of 28 seconds. Hurrah! It beats the record set by Sebastian Vettel and also past champions such as Lewis Hamilton , Michael Schumacher etc.. for they have never raced a Lego Mindstorm robot in Uni Melb thus they DNF.(go google if you have no idea what is DNF)
Now I would like to turn your minds to the world of physics. Its blows mind and I was pretty sure everyone’s jaw were stuck to the ground thanks to the latest lecture regarding relativity.
The man behind it all. Einstein.
He have solved so many problems that were once inconceivable.
Problem 1:
We are poor. We have a house which is only 1m long but our bed is 2m long. What to do ?
Answer: Accelerate the bed to near the speed of light, and the bed will contract in length, thus you can fit it in your house. (assuming bed does not burn from friction travelling at near speed of light, house not moving, the people only wants to be on the bed for a few nanoseconds before bed flies out of the house again)
Problem 2:
They say women can live longer than man. I want to live longer than my wife. What can I do?
Answer:
Go on a space ship and fly to 80% of speed of light and return. Moving clock are always slower, so you age slowly in comparison to your wife, thus you will outlive her.
Problem 3:
I am a huge (insert artist/band name here) fan/friend(for kuo wei,) , and I want to be the first person to hear their new single playing on the radio. What can I do?
Answer:
Its easy! Even if you stand equal distance from the speaker/radio/singers' mouth, you can still be the number eins fan by changing your point of reference. IF, you have a father who owns a spaceship that travels at close to the speed of light, he will see you hearing the music first compare to the other losers who don’t have such a father. The other loser might think they heard it the same time as you, but your father on the spaceship will see you hearing it first! Awesome isn’t it?
If you were confused/lost/astounded/still confused/no idea what I am blabbering about, its totally fine! Its just the 3 principle of Einstein’s Special Relativity.
-
Moving objects are shorter
-
Moving clocks are slower
-
Simultaneity is relative.
Ok that would be all.
Disclaimer: Not all diagrams are true to the original situation and the the questions were not posed by the Uni Melb lecturers, rather a alternative idea proposed by me.
