Where should we explore next in our solar system?

I believe that NASA should focus on Europa, Jupiter’s moon, instead of Enceladus, Saturn’s moon for future NASA missions

  • Scientists consider Europa a “top candidate” by NASA for life because of its optimal conditions for life as we know it.
  • Abundance of warm, liquid water under its thick ice shell
  • Hubble Space Telescope has detected evidence of plumes on both Europa and Enceladus.
  • The plumes could be caused by water interacting with rock, creating the perfect environment for micro bacteria to fester.
  • Both Europa and Enceladus has carbon dioxide and hydrogen in its atmosphere, so it could be that underwater organisms are producing methane gas.
  • A space scientist, Voytek, said her bet is still on Europa for potential life. “Europa is much older than Enceladus, and any potential life would have more time to emerge.”
  • NASA suggests that “the moon of Saturn(Enceladus) has conditions that could sustain life as we know it.”
  • Jupiter is also closer to Earth than Saturn, so the spacecraft sent there would not take so much time and money to find alien life.

So, Europa has a larger possibility of having alien life, than Enceladus. Though they have the similar conditions, such as a warm sea under their thick layer of ice, plumes that creates possible harbors for micro bacteria and a

and NASA hopes to find Non-earth life, Europa should be the focus of future NASA missions instead of Enceladus.

Food rush @ the Hutong

I chose this one-day project because I like food. Especially Chinese food.

Originally, I voted for the Yunnan food, since I could not eat the spicy food of Sichuan. However, more people voted for Sichuan food. I kinda dreaded the day that we made the Sichuan food, since I had an image of a Sichuan dish, sprinkled with chili and pepper, searing to the mouth, in my mind.

This was what i I imagined.

However, I was really interested in the tea. I really love drinking tea, to smell the thick aroma of the fragrant leaves. Slowly unraveling in the clear water, unleashing its dark colors to paint the water dark red and green. Though I already knew how to make tea, I still wanted to see how others like their tea. Sadly, my little bubble fantasy was pieced through and popped.

Apart from the tea, I was not that satisfied with the food making, though we made great beef stew (bit too spicy and cooked the meat a bit too much).

I think our biggest success was the noodles (Ji Si Liang Mian).

It may have taken a while to get to my mouth, but I’ve found the best noodles on the planet. The ingredients were freshly prepared by our instructors, and we had set to making it as soon as we were told!

The dish looked absolutely stunning when it was set on our tables. I could not believe that I was the maker of this dish. I felt like I was in my family’s kitchen again, eating the food that I made. The noodles went fantastically well with the soy sauce! With the peanut that we chopped up, it was soft and crunchy at the same time and the addition of soy sauce, vinegar and sugar made the slightly bland taste much more colorful.

That, I could say, was the better part of our culinary experience.

 

After eating, we made tea packages. We made our own tea and designed its packaging. However, I did not think that the price for the tea packaging was reasonable. We had paid 120 RMB for this. And all we got was some stickers, a bag and some tea!

Now, I am not a professional of tasting tea, I have searched up at numerous websites for the prices of the tea that they provided us.

for each 500 grams:

  • ¥215.00 for honeysuckle
  • ¥596.37 for black tea (https://shop.dilmahtea.com/tea-types/black-tea/black-tea-pure-darjeeling-single-region-600g-leaf-tea)
  • ¥350 for the dried lily flower (https://www.teasenz.com/lily-tea-orange-flower#.XFObgs8zbpA)
  • ¥330 for the white chrysanthemum (https://www.amazon.com/GOARTEA%C2%AE-Organic-Premium-Chrysanthemum-Natural/dp/B010SQH0EE/ref=pd_lpo_vtph_tr_img_1?_encoding=UTF8&psc=1&refRID=B7WR4E66ZPFMF1KVY4FN)
  • ¥93 for the goji berry(https://www.amazon.com/dp/B00BSD9C5M/ref=sspa_dk_detail_3 psc=1&pd_rd_i=B00BSD9C5M&pd_rd_w=hZxAT&pf_rd_p=21517efd-b385-405b-a405-9a37af61b5b4&pd_rd_wg=gEXjS&pf_rd_r=JBF9ENS6XY2NT1KTETQB&pd_rd_r=74f1be4f-25bc-11e9-9ef7-8b5dde2c9ca4)
  • ¥1 for the sugar

However, we were only allowed to take a little bit of the tea.

  • 2 teaspoons of black tea (4 grams)
  • 3-5 flowers, (5-6 grams)
  • 3-5 flowers,  (5-6 grams)
  • 10-15 goji (8 grams)
  • 2 sugar cubes (6 grams)

Say that you chose the most expensive flowers, so that the tea will be made of black tea, 5 dried lilies, 5 dried white chrysanthemum, 15 goji and 2 sugar cubes. The total cost would be¥4.7 (black tea) + ¥4.2(lilies) + ¥4 (white chrysanthemum) +¥1.4 (goji) + ¥0.012 (sugar)= *drumroll please*

¥14.312! Which is a ¥105.7 difference from the 120 we paid.

Well, you might say that the shop gave us stickers and markers to draw.

well, the markers barely had any ink and the stickers are sold in rolls, so taking 2 stickers for each person amounts to almost no decrease in the sticker roll.

I have learnt in this one day, aboutthe lengths people take to make money. I am appalled. It is my hope that our school does not engage in the Hutong one day activity again. It is a great rip-off.

The expectations that I had were switched to disappointment.

Some difficulties I faced was the sanitary issues. Some people in our group were not considerate at all. One wiped his nose and then started tearing up the chicken for our noodles. Another carelessly threw the lettuce into the cooking stove, so that some fell to the ground. Couldn’t they realize that they were sabotaging the safety of our food?

Another challenge was the number of stoves. I had expected us to work in small groups on our own stoves. However, that was not the case. We only had four stoves, to be shared by two groups of about 10 people each. There were some people in our group ( two or three) that could not eat that much spicy food. And because we had only two stoves for our group, we could not eat non-spicy food.

One stove was for extremely spicy food, and the other was for slightly spicy food. I had suggested that we can have one stove for non-spicy food, but the instructor disagreed, saying that it was “for the greater good”. WELL, couldn’t the people that like food of middling spice just mix the spicy and non-spicy stew up!

Is there extra terrestrial life?

Is there extra terrestrial life?

Are we alone in this universe? These are the questions that many has wondered about. I believe that there is extra terrestrial life, yet, is their existence good or bad for us?

For a long time, scientists have looked into our closest stars to find alien life. Yet they found none. Could it be that we are alone? Or did we not look far enough?

Earth is very special. It is just the right distance from the sun for life to evolve, giving life the right temperatures to survive and thrive. It also has an atmosphere, which keeps water and air in and the vacuum of space out. Chances are, another earth forming would be one in a million.

About 80% of star systems are expected to have planets around them, it’s estimated that there are approximately 60 billion rocky, habitable-zone planets in our galaxy alone. What could alien life mean for us? Personally, I think that it would end poorly. Alien kind could not be the same as humans, so we would have no way to communicate. We could be so far away that it takes tens of years to transmit a message. That situation would be like two nations, on opposite ends of the earth trying to communicate with each other before the telephone.

Suspicion of each other would rise, and you would suspect that the other life form suspects you. and the other life form would suspect that you suspect them suspecting you. So on and so forth.

This circle of suspicion would cause great drifts lying between our worlds, likely causing an galactic war.

How big is our solar system?

Our solar system is GIGANTIC!

But how big is it really?

For example, the largest planet in our solar system, Jupiter, is 142,800 km in diameter, which is more than ten Earth’s diameter added together! But compared to the Sun, with an astonishing diameter of 1,392,000 km, gives off all the light than our solar system needs.

However, a long string of numbers does not seem like anything, to give you a perspective, when you have a scale of 1cm=50,000km, the distance between Pluto,(the furthest from the sun.) would cover the length of 10 football courts!

When our solar system is so big, how big is a galaxy? How big is space, which contains millions of galaxies, with millions of stars like our sun, trillions of planets orbiting the stars. It really is a question to wonder, the longer we look at the stars, the smaller and more insignificant we seem.
