what planet is this guy living in??? The teachers my daughter's primary school EMPHASIZE keywords so much.... PSLE science today is just keywords. The marking scheme itself is keywords based... alternative answers... err are you going to risk it ??? PSLE can "show our moral character" ???? This guy really come across as full of ****

Instead of all the moaning and b*tching about people and the stupid things they do, I decided to start a thread on science and engineering, so that we can all learn more about the world around us. Do feel free to share videos that shed light on the workings of our world, so that we can all benefit from the knowledge. First up, something that quite a lot of us use daily. GPS! (Actually, more on the atomic clock than GPS) https://www.youtube.com/watch?v=p2BxAu6WZI8 Secondly, for all of you who love to drink soda / canned drinks, ever wondered why the can was designed in such a manner and how it was made? Wonder no more! https://www.youtube.com/watch?v=hUhisi2FBuw Check out more of this guy's channel! I just started watching him last night, and now I can't stop! Hahahha..

I was enjoying the many relevant points raised, both for and against....only to read this.. "I'm laughing at this juvenile thread. I am locking this thread. " There was no flaming, no vulgarity, just a lot of earnest people trying to make their points heard. And over a topic that many people feel fervently about. So I don't really get what was juvenile about the thread. Could the mods please exercise some consideration. The power to censor and stop discussions should be used sparingly.

Another close called after Ison .... Yahoo news: Earth marks close encounter with enormous asteroid REUTERS - An asteroid estimated to be the size of three football fields whizzed close to Earth on Monday, roughly a year after one exploded over Russia and injured 1,200 people. Slooh Space Camera tracked the approach of the asteroid as it raced past the planet at about 27,000 mph (43,000 kmph), starting at 9 p.m. EST (2 a.m. GMT, February 18), the robotic telescope service said in a statement on Slooh.com. The Dubai Astronomy Group provided Slooh photos of the part of the sky where the rock was expected to be seen, but its motion could not be picked out immediately in a live webcast against the backdrop of night-time stars. The 295-yard (270-m) asteroid was streaking past Earth at a distance of about 2.1 million miles (3.4 million km) little more than a year after another asteroid exploded on February 15, 2013, over Chelyabinsk, Russia. That asteroid injured 1,200 people following a massive shock wave that shattered windows and damaged buildings. Chelyabinsk region officials had wanted to mark the anniversary by giving a piece of the meteorite to each 2014 Winter Olympic athlete who won a medal on Saturday at the Sochi Games. However, the International Olympic Committee at the last minute said it could be done only after the games and separately. Slooh's flagship observatory on Mount Teide in Spain's Canary Islands was iced over and unable to be used for the 2000 EM26 viewing, Paul Cox, Slooh's technical and research director, said on the one-hour webcast. "We continue to discover these potentially hazardous asteroids - sometimes only days before they make their close approaches to Earth," Cox said in a statement before the show. He added, "We need to find them before they find us!" Its seem we are getting closer to extinction as years gone bye with so many 'BIG' rocks flying pass our mother Earth and each one getting nearer .... This one not even spotted until last minutes and some telescopes observing the universe were frozen cos of unexpected winter storms.

My child was given a science question today :- Qn. The Earth rotates around the Sun. True / False / Depends Explain. My answer is False. The Earth revolves around the Sun in around 365 days but rotates on it's own axis in about 24 hours. Any other answers ?

Hi bro and sis, Does anyone knows how much is the season parking fee? No info online. Thank you

I know sound travel by the transferring of mechanical energy from atom to atom. And i also know sound travels faster in denser material for example, sound will travel faster along along a steel pipe faster than in air. so my question 1) when i am under water in the swimming pool, and my friend outside of the water shouts at me - why is that i cant hear him so well? i thought sound waves should travel faster in water? 2) when my and my fren are underwater in the swimming pool, my friend yells are me. why is that i cant hear well either? as compared to if he yells at us when were are both on land

Let see how fast you get the right answer. Primary school Math & Science are really tough nows a day.

Does anyone have an idea? tia.

Hello BRos Does any one know if there is a camera at this junction of Jurong Town Hall Rd and Science Centre. I turned right from Science Centre Rd onto Jurong Town Hall Rd when light turned red. Dont remember seeing a green arrow ( right ) light. Thank you all. I believe there was a url showing where the cameras are in Sg. Thanks yall Jeff

A long article but well worth a read, esp if you are of Christian faith. An actual discussion between a philosophy professor and his students 'Let me explain the problem science has with religion.' The atheist professor of philosophy pauses before his class and then asks one of his new students to stand. 'You're a Christian, aren't you, son?' 'Yes sir,' the student says. 'So you believe in God?' 'Absolutely. ' 'Is God good?' 'Sure! God's good.' 'Is God all-powerful? Can God do anything?' 'Yes' 'Are you good or evil?' 'The Bible says I'm evil.' The professor grins knowingly. 'Aha! The Bible! He considers for a moment. 'Here's one for you. Let's say there's a sick person over here and you can cure him.. You can do it. Would you help him? Would you try?' 'Yes sir, I would.' 'So you're good...!' 'I wouldn't say that.' 'But why not say that? You'd help a sick and maimed person if you could. Most of us would if we could. But God doesn't.' The student does not answer, so the professor continues. 'He doesn't, does he? My brother was a Christian who died of cancer, even though he prayed to Jesus to heal him. How is this Jesus good? Can you answer that one?' The student remains silent. 'No, you can't, can you?' the professor says. He takes a sip of water from a glass on his desk to give the student time to relax. 'Let's start again, young fella. Is God good?' 'Er..yes,' the student says 'Is Satan good?' The student doesn't hesitate on this one. 'No.' 'Then where does Satan come from?' The student falters. 'From God' 'That's right. God made Satan, didn't he? Tell me, son. Is there evil in this world?' 'Yes, sir.' 'Evil's everywhere, isn't it? And God did make everything, correct?' 'Yes' 'So who created evil?' The professor continued, 'If Go created everything, then God created evil, since evil exists, and according to the principle that our works define who we are, then God is evil.' Again, the student has no answer. 'Is there sickness? Immorality? Hatred? Ugliness? All these terrible things, do they exist in this world?' The student squirms on his feet. 'Yes.' 'So who created them?' The student does not answer again, so the professor repeats his question. 'Who created them?' There is still no answer. Suddenly the lecturer breaks away to pace in front of the classroom. The class is mesmerized. 'Tell me,' he continues onto another student. 'Do you believe in Jesus Christ, son?' The student's voice betrays him and cracks. 'Yes, professor, I do.' The old man stops pacing. 'Science says you have five senses you use to identify and observe the world around you. Have you ever seen Jesus?' 'No sir. I've never seen Him.' 'Then tell us if you've ever heard your Jesus?' 'No, sir, I have not.' 'Have you ever felt your Jesus, tasted your Jesus or smelt your Jesus? Have you ever had any sensory perception of Jesus Christ, or God for that matter?' 'No, sir, I'm afraid I haven't.' 'Yet you still believe in him?' 'Yes' 'According to the rules of empirical, testable, demonstrable protocol, science says your God doesn't exist. What do you say to that, son?' 'Nothing,' the student replies. 'I only have my faith.' 'Yes, faith,' the professor repeats. 'And that is the problem science has with God. There is no evidence, only faith.' The student stands quietly for a moment, before asking a question of His own. 'Professor, is there such thing as heat?' 'Yes. 'And is there such a thing as cold?' 'Yes, son, there's cold too.' 'No sir, there isn't.' The professor turns to face the student, obviously interested. The room suddenly becomes very quiet. The student begins to explain. 'You can have lots of heat, even more heat, super-heat, mega-heat, unlimited heat, white heat, a little heat or no heat, but we don't have anything called 'cold'. We can hit down to 458 degrees below zero, which is no heat, but we can't go any further after that. There is no such thing as cold; otherwise we would be able to go colder than the lowest -458 degrees. Every body or object is susceptible to study when it has or transmits energy, and heat is what makes a body or matter have or transmit energy. Absolute zero (-458 F) is the total absence of heat. You see, sir, cold is only a word we use to describe the absence of heat. We cannot measure cold.. Heat we can measure in thermal units because heat is energy. Cold is not the opposite of heat, sir, just the absence of it.' Silence across the room. A pen drops somewhere in the classroom, sounding like a hammer. 'What about darkness, professor. Is there such a thing as darkness?' 'Yes,' the professor replies without hesitation. 'What is night if it isn't darkness?' 'You're wrong again, sir. Darkness is not something; it is the absence of something. You can have low light, normal light, bright light, flashing light, but if you have no light constantly you have nothing and it's called darkness, isn't it? That's the meaning we use to define the word. In reality, darkness isn't. If it were, you would be able to make darkness darker, wouldn't you?' The professor begins to smile at the student in front of him. This will be a good semester. 'So what point are you making, young man?' 'Yes, professor. My point is, your philosophical premise is flawed to start with, and so your conclusion must also be flawed.' The professor's face cannot hide his surprise this time. 'Flawed? Can you explain how?' 'You are working on the premise of duality,' the student explains..'You argue that there is life and then there's death; a good God and a bad God. You are viewing the concept of God as something finite, something we can measure. Sir, science can't even explain a thought.' 'It uses electricity and magnetism, but has never seen, much less fully understood either one. To view death as the opposite of life is to be ignorant of the fact that death cannot exist as a substantive thing. Death is not the opposite of life, just the absence of it.' 'Now tell me, professor. Do you teach your students that they evolved from a monkey?' 'If you are referring to the natural evolutionary process, young man, yes, of course I do.' 'Have you ever observed evolution with your own eyes, sir?' The professor begins to shake his head, still smiling, as he realizes where the argument is going. A very good semester, indeed. 'Since no one has ever observed the process of evolution at work and cannot even prove that this process is an on-going endeavor, are you not teaching your opinion, sir? Are you now not a scientist, but a preacher?' The class is in uproar. The student remains silent until the commotion has subsided. 'To continue the point you were making earlier to the other student, let me give you an example of what I mean.' The student looks around the room. 'Is there anyone in the class who has ever seen the professor's brain?' The class breaks out into laughter. 'Is there anyone here who has ever heard the professor's brain, felt the professor's brain, touched or smelt the professor's brain? No one appears to have done so. So, according to the established rules of empirical, stable, demonstrable protocol, science says that you have no brain, with all due respect, sir.' 'So if science says you have no brain, how can we trust your lectures, sir?' Now the room is silent. The professor just stares at the student, his face unreadable. Finally, after what seems an eternity, the old man answers. 'I guess you'll have to take them on faith.' 'Now, you accept that there is faith, and, in fact, faith exists with life,' the student continues. 'Now sir, is there such a thing as evil?' Now uncertain, the professor responds, 'Of course, there is. We see it everyday. It is in the daily example of man's inhumanity to man. It is in the multitude of crime and violence everywhere in the world. These manifestations are nothing else but evil.' To this the student replied, 'Evil does not exist sir, or at least it does not exist unto itself. Evil is simply the absence of God. It is just like darkness and cold, a word that man has created to describe the absence of God. God did not create evil. Evil is the result of what happens when man does not have God's love present in his heart. It's like the cold that comes when there is no heat or the darkness that comes when there is no light.' The professor sat down. If you read it all the way through and had a smile on your face when you finished, mail to your friends and family with the title 'God vs Science' PS: the student was Albert Einstein Albert Einstein wrote a book titled God vs Science in 1921.... "Dear God, grant me the ability to reject the things about me that are not true, the humility to accept the things that are, and the discernment to know the difference."

Anyone care to explain and confirm the attached P6 science multiple question. A or B or C or D My 1st answer is 'C'. In P6, Kinetic Energy is taught to be an energy force in motion, which depend on the object mass & velocity. Thanks.

As above, looking for my daughter, anybody can recommend. Thanks.

beware: for people who works at science park I science hub area, 6.15pm today saw an officer in white(LTA?? or conductor, don't know how you call it) using a digital camera to take pictures of a silver toyota altis and a silver (i think) Getz, black matrix behind the Getz - driver quickly drove away, escaped. All cars were parked at the empty space right outside Science Hub. Sigh, does it means that both cars kan na fine for illegal parking? Officer uncle so strict, park a bit also cannot . Anyway, parking for 1st hr at science hub only 50cts, if only a short while, no point park outside and kan na this........sometimes find singapore too strict, 一点人情味都没有

Check the link below. I think he has a very good idea and this is an improvement in the right direction for the internal combustion engine but India is doing it wrong relegating technology as something dark and evil. http://www.popsci.com/popsci/futurecar/art...79464-1,00.html
