Theme of MICSS Science Camp 2009 – 天工开悟

Attending to MICSS Science Camp 2009 in Foon Yew High School, Kulai as a counsellor was a great pleasure. I can focus more on making friends instead of striving hard for prizes. Most importantly, it was a great chance to widen our perspective on science and to realise what we have in mind is just a fraction of the whole puzzles.

The main program of the science camp was the lectures by renowned professors. They were Prof. Wei-Hsin Sun, Prof. Chia-Wei Lee and Prof. Shun-Fen Tzeng. Their talks covered topics ranging from astronomy to life science. It was a pity that they were not given enough time to go deep into their exciting stories. However, I think their talks were impressive enough to encourage us to dig into them ourselves.

The second night of the camp, I joined Dr.Chong from USM for the “Night talk”. I was really amazed that he is so energetic and passionate. I can hardly find anybody else on par with him. He gave us a talk on the topic – The Search for More Extra-solar Planets – E.T. Where Are You? Wow! Interesting huh? Yeah, jia bueh liao! (Hokkien).

Dr.Chong pointed us the Alpha Centauri. Wow!

Right after that was stargazing party. It was even more fun with the present of Dr.Chong. He was like a boy running on the field with endless energy. He distributed lots of star charts and almanac to us and showed us the constellations by green laser. He also showed us the Meade MySKY which functioned as an electronic starchart. I was his assistant but I went away to take Prof. Sun’s autograph. Haha… Sorry about that Dr.Chong. Back to the stargazing party, the telescopes were not as many and powerful as last year. The weather was not very nice though. In fact, it was not a failure but it was not great enough to allure people to pursue astronomy as a hobby.

Dr.Chong said, “Fuiyoh… Don’t underestimate this cheap-looking water rocket. It can fly up to 150 meters high! No joke!”

Earlier the day, I also joined Dr.Chong for the mini water rocket DIY session. I loved to learn from him. He was such a high spirit, energetic and humorous professor. I can’t help laughing throughout the workshop. He is a real funny guy. The water rocket can be made under RM5. We just need plasticine, masking tape, wood made chopsticks and 2 7-up bottles. The launcher can be done with RM20. The designs of the water rocket and launcher are proven to be effective. I will ask for Dr.Chong permission if I can upload the guide of making water rocket.

The Universe movies were visually nice. However, most of us were not happy with the Bahasa Malaysia dub. The movies would be more interesting if they were played in English.

I have a little complain here. The food was considered below average. It was oily and boring. The breakfast, snack and supper were almost the same for the whole week. Some said that it’s not green to use paper plate (Yes, we had our food with use-and-throw tableware). Do you think it will be greener if we use reusable tableware? Save trees and petroleum or water? Discuss, please.

Congratulations! You guys did a great job! I am really proud of being the counsellor of Team 7.

I will have a gallery working later which shows all the photos I took. Stay tuned!

C02 Emission, Birth and Death Rate of Your Country

I just stumbled across this interesting facts about the earth and I think it shall worth a read. BreathingEarth tells us about the CO2 emission, birth and death rate of human on Earth by country.

In Malaysia, every 55.6 seconds, a new life is born and every 4.1 minutes a person dies. 1000 tonnes of CO2 is emitted every 3 minutes.

I accidentally came across the facts of Spain. The birth rate and the death rate are exactly the same which is 1.3 minutes each.

The country that releases the most CO2 is United States of America which is every 1000 tonnes of CO2 per 5.3 seconds, second by China at 6.4 seconds. Wow… terrific… I think if we do not reduce carbon emission promptly, disasters are ahead of us soon.

Hubble Space Telescope Upgraded

Hubble Space Telescope

Our beloved Hubble Space Telescope (HST) launched 19 years ago has now been upgraded by NASA space shuttle mission STS125. The Servicing Mission 4 is Hubble’s last repair mission, so the crew members of STS125 riding on space shuttle Atlantis are the astronauts who touched HST one last time. After the refurbishment of HST, it is expected to work fine until 2014 and by then, it will be replaced by James Webb Space Telescope (only on infrared).

Hubble Space Telescope is now equipped with 2 new instruments, Wide Field Camera 3 (WFC3) and Cosmic Origins Spectrograph. Its Advanced Camera for Survey down in 2007 and Space Telescope Imaging Spectrograph failed in 2004 are now back to online. HST is also reloaded with new batteries, six new gyroscopes, a refurbished fine guidance sensor, a new outer blanket layer and a soft capture and rendezvous system.

The WFC3 has higher resolution and wider field of view than Wide Field and Planetary Camera 2 (WFPC2). It will be used to study dark energy and dark matter, formation of individual star and discover extremely remote galaxy which helps us know more about the early universe. The COS is key to understand galaxy evolution, the formation of planets, the rise of the elements needed for life, and the “cosmic web” of gas between galaxies as spectrograph can reveal the elements by breaking lights into spectrum.

Direct evidence of dark matter. Imaged by HST.

Hubble Space Telescope has long been delivering Earthlings amazing astronomical discoveries and stunning pictures. Now, its ability has been enhanced to a further step that it can do 10x better than before. The secrets of the dark matter and more exoplanets may soon be revealed. We shall anticipate more jaw-dropping discoveries by HST.

I am sure that the info above is not able to satisfied your hungers, read NASA SM4 Essentials. Don’t miss it!

By the way, I am curious about the privacy that the only female astronaut, K. Megan McArthur has. What do you think?

Night 2: Kluang Mall

A kid was looking at the Great Orion Nebula

Kluang Mall, 4 April 2009 – First, I would like to express my appreciation towards the Kluang Mall management as they were kind to provide us a space at the main entrance for free. They also arrange security guards to standby and make sure the vehicles never run into us.

The weather was mediocre when we setup the telescope on 7pm. Bright astronomical objects like Moon, Sirius and Canopus were visible but others were not without optical aid. It was getting worse as the time passed through. Moon was blocked by the shopping mall, Sirius and Canopus were partially blocked by the cloud and Great Orion Nebula was getting dimmer and dimmer.

Papa, please put away your hand

There was a huge crowd but the weather did not cooperate. Many of them were dissapointed. Even though we had 514 people looked through the scope, we were not convinced that we did a great job. If there is any such situation in the future, I think we should cut the event or run the backup plan since our motivation is to let them enjoy the beauty of the night sky.

Well, let’s look at the pictures.

Lots of kids around.

“Do I look more pretty or the stars?” The girl said.

Last but not least, I am so grateful that these guys work with me on such meaningful events. Thank you all!

Night 1: GIANT, Sri Kluang

Robin Lee — Mon, 11 May 2009 18:06:03 +0000

GIANT Hypermarket, 3 Apr 2009 – At 6.30pm, the weather was cool and cloudy due to the afternoon heavy downpour. With the astronomy enthusiasm burining in our hearts, we insisted on setting up the telescopes. Just after 20 minutes, the wanning-gibbous-moon light pierced through the cloud. A good sign, indeed.

From left to right: Meade 8-inch-LX90, Celestron Celestar 8 and Orion Skyquest XT8i

The weather was getting better and better. The cloud was cleared and the transparency improved as well. Sirius was once again the brightest star on the sky. Thanks to the cooperating weather, we observed the Moon, Saturn, Great Orion Nebula (M42), The Seven Sisters aka Pleiades (M45) and plenty of star clusters such as the Jewel Box. Moon and Saturn were the most appreciated celestial bodies as they were bright and rich in features.

Shyh Tzer was showing a curiousity driven visitor where was my 8 inch telescope pointing at.

There were three 8 inch telescopes serving the public during the night. The 8 inch LX90 and the Orion XT8i were the most popular among the three. The reason that the Celestron Celestar 8 was not well accepted was due to its eyepiece orientation and the height of the telescope. As it was on a wedge, it was pretty hard for adult to look through it. However, it was unexpectedly suitable for little kids.

We had roughly 400 visitors for the night. This sounds great to us as the figure even surpasses the last year number. Though I have to admit that there may have duplications among the numbers.

In conclusion, this was a great warm up.
