Every day will be a big pile of bullshit if I focus on only problems I have come across.
- That suddenly-broken-down external hard disk.
- Those never-replying and always-busy kids.
- Things that I do not enjoy but have to do.
- Things that others do not enjoy but I have to make them do.
Many many of them if I have to recount every piece of them.
But life is not the summation of every problem, they say. Or at least, that is not the meaning of life. The meaning of life is the summation of every tiny little event that makes ones happy.
- The hard disk worked again with no apparent reasons.
- The introvert kid finally dared to phone me (because I came late lol).
- The same introvert kid shared with me his experience last week.
- The patrol leader frankly and boldly told me his and his patrol's thoughts.
- Some scouts that I taught in Astronomy course still remember me and called me Fan Sir.
- One of them asked for more posts on the Astro Club Facebook page.
- Girl scout from QCOBASS feeling proud when coming across Scout and Scouter from QC.
- She shared her pride on Facebook and we became friends.
- A very big glass of iced lemon tea.
- Having meals with my family.
- Listened to George Lam in TVB.
- Having a group of enthusiastic scouters to share my frustration with.
- Still alive.
- And you. My irreplaceably lovable girlfriend.
Recollect those small things. It is always something small that build something big. And, look at them. What more can I ask for?
Since the universe is a big place, we could easily get lost. So, we will need signposts to give us a sense of scale. The acrobat ring is 1 meter wide, the crowd is 10 times wider, 10 meters across, larger by one power of ten. Now, with every step, every ring, we travel 10 times farther from Venice, and our view of the universe is 10 times wider.
The 100-metre ring is around St. Marks, and 1,000 metres, 1 kilometer, the city centre. As our speed increases, 4 steps – 4 powers of 10 – reveal all the islands of Venice, the Adriatic Sea, and the mainland in Northern Italy.
If we visualize the paths that the nine (note: eight) planets take in their orbits around the Sun at 13 steps from St. Mark’s Square, the entire solar system comes into view.
And with 15 steps – 15 powers of 10 – we can see our sun is just another star. From here on, our voyage will be measured in light-years – the distance light travels in an entire year. Only now do we fly past our nearest neighbor stars almost 5 light-years away. The same journey at the speed of today’s spacecraft would last 100,000 years.
As we cross the perpetual night, our voyage takes us up and out of our Sun’s neighborhood near the edge of a great pinwheel of stars. The Milky Way is actually a (note: barred) spiral galaxy and our own Sun is just one of a hundred billion stars in it. At this immense scale, 23 powers of 10, each shining light we see is not a star but an entire galaxy composed of countless stars.
Astronomers have discovered that the galaxies are flying away from one another. The universe is expanding. Our own galaxy, and all the others form clusters and superclusters of stupendous size – hundreds of millions of light-years across. And here, about 15 billion light-years from Venice, we approach the outer limits of the visible universe. What lies beyond this cosmic horizon, we cannot see. And do not know.
我絕對也擁抱這些宗教所持的某一些理念,因為大部分這些理念都是導人為善,而且是普世價值,不贅。但同時也必須指出,這並不代表我便需要或已經信奉了某一個宗教,也不代表所有信奉此宗教者能夠實行這些理念。上兩句所說的,亦說明了「某宗教」及「該宗教所擁抱的價值」兩者並沒有若且僅若(if and only if)的關係,正正也是我認為不需要相信任何宗教的另一原因。
他的孩子還未滿歲,這位爸爸已經在擔心他將來的學業。他談到或許自己需要多讀一下中學的課,萬一將來孩子遇到不明白的地方時,也有爸爸為他解答一下。我說,未免太誇張吧。上中學的時候,父母能夠為兒女的學業幫上多少忙?父母也不是百科全書,幾十年沒用過Phy Chem Bio History Geog的知識,難道還可以為兒女解答問題嗎?我說,實話,上中學以後,爸爸除了Maths Phy外也沒能幫得多少,媽媽更完全派不上用場。不明白便找老師同學吧,反正一定有人懂。他想了片刻,答我,「這是因為你在皇仁讀書而已。」
