The Greek Alphabet

Forked from page(hmm I don’t know why they deny access from mainland China). I found that MIT don’t delete pages for PhD students even a student has graduated long ago. That is a culture Chinese universities really should learn. I open up the page everyday I start working, especially in cases where latex is not applicable. To reassure, I paste the whole page here in case of a server failure in MIT.

Α α alpha a father
Β β beta b
Γ γ gamma g
Δ δ delta d
Ε ε epsilon e end
Ζ ζ zêta z
Η η êta ê hey
Θ θ thêta th thick
Ι ι iota i it
Κ κ kappa k
Λ λ lambda l
Μ μ mu m
Ν ν nu n
Ξ ξ xi ks box
Ο ο omikron o off
Π π pi p
Ρ ρ rho r
Σ σ, ς sigma s say
Τ τ tau t
Υ υ upsilon u put
Φ φ phi f
Χ χ chi ch Bach
Ψ ψ psi ps
Ω ω omega ô grow

Sigma (σ, ς):There are two forms for the letter Sigma. When written at the end of a word, it is written like this: ς. If it occurs anywhere else, it is written like this: σ.

Upsilon (υ):In the above table, we suggest that you pronounce this letter like “u” in “put”. The preferred pronunciation is actually more like the German “ü” as in “Brücke”, or like the French “u” as in “tu”. If you do not speak German or French, don’t worry about it, just pronounce it the way the table suggests.

Xi (χ): This is the same sound as “ch” in “Bach”, which does not sound like “ch” in “chair”. The same sound occurs in the Scottish “Loch”, as in “Loch Lomond”, or the German “ach!”.

Footnote 1: Other pronunciation schemes
To be fair, we should mention that there are several different ways to pronounce Greek. We are teaching the Erasmian pronunciation for now. At some point in the future, we may add pages to teach some of the other pronunciations. Here are the main ways that Greek is pronounced:

Erasmian pronunciation. This is the pronunciation used here, and is probably based on the pronunciation used by a Renaissance scholar named Erasmus, who was the main force behind the first printed copies of the Greek New Testament. The Erasmian pronunciation is probably different from the way Greek was pronounced at the time of the New Testament, but it is widespread among scholars, and it has the advantage that every letter is pronounced, which makes it easy to grasp the spelling of words.
Modern Greek pronunciation. This is the way Greek is pronounced today in Greece. Some people prefer to teach this pronunciation for New Testament Greek as well. I initially learned the modern Greek pronunciation, but had difficulty learning to spell words, so I switched to the Erasmian. Modern Greek pronunciation is probably more similar to New Testament Greek pronunciation than Erasmian is, but not identical.
Reconstructed New Testament Greek pronunciation. There are some scholarly books which attempt to reconstruct the original pronunciation of New Testament Greek, and they have reached the point that there seems to be fairly widespread agreement on the original pronunciation. As far as I know, nobody ever teaches this pronunciation. Incidentally, since there was a large variety of Greek dialects, there was no single way to pronounce Greek even in the New Testament era.
Fraternity, Physics, and Calculus pronunciation. This is the way your physics teacher spoke Greek, and he learned this pronunciation in his fraternity. Next time you hear a physics teacher pronounce Greek, laugh and look superior.

Additional forms of variants from wikipedia:

epsilon \varepsilon \, Εϵε

Theta \theta \vartheta \, Θθϑ

Sigma \sigma \varsigma \, Σσς

Phi \phi \varphi \, Φϕφ

ϵ ϑ and ς appear quite often and are quite less explained by greek alphabet.

Stick to it

Hold on and stick to it. The problems will be solved in just a minute as long as you hang on for some time. It is like a change of temperature when the days are so hot and you are even not willing to go out and fetch the delivery package. You could never imagine someday the temperature would change drastically from hot to cold. Just take hot as your problem, the key to solve it lies on the days to take changes. So when problems come, there is no need to be anxious on when one can get rid of it or figure out a roadmap on day one. When the days come, the problem cures itself. This is what I recently learnt from experience.

Recently, I watched the speech that Steve Jobs delivered in 1992. He mentioned that technology windows will be out there for about 5 years. And every serious product has been the result of 5 years of prototyping. What resonates with me is that 5 years of prototyping is just an example of waiting for the temperature to turn around. You may say you don’t have the time to do it today. But it won’t be the case afterwards.

As a summary, I think that persist along the miserable path is the right way to get rid of the miserable path, since it won’t be always so as days coming along.

There are 2 technical details that helps. First, always believe that good things will happen. Elon Musk once said in an interview, I’d rather be optimistic on wrong rather than pessimistic on right. Second, train the ability to face the emotion storm directly. Experience tells that you can observe it as if from the third person vision, watch its shape as if it should have a shape of some kind.

Crucial things when a scholar is on his own

When a graduate student is supervised by a professor, he may be more developing the routines and basic structure of starting a research, in which case mostly he is restricted to the field the supervisor resides. However, when he graduates, all the restrictions disappears and he can search for his research interest on his own. At this moment, new challenges rises along with freedom of choice.

1. Decide on a promising research field that matches the development of the country and the researcher’s interest. Is the field critical to the country’s need so the research will be potentially funded by big money? Does the field actively studied by in recent 3 years? Does the field studied by great guys such as ones in MIT? Do recent works publish on top tier journals such as IEEE network? Do this field studied intensely in my country so I will have to face fierce competition? Is there any research field that advances relatively more in the US but for some reason ignored in my country so I can get funded effortlessly?

Most scholars follow the stereotype that their supervisor define and never change a bit in his research career. When most scholars behave like that, the outline of plan for research centers become nothing but the same old stuff wrapped up in new packings. After several years, nothing is genuinely implemented and the outline is actually badly fulfilled albeit a kind resolution.

2. Once you decided the field you are going to invest your time and effort in, the next important thing is to propose a good question. The question lies on the fast grasp on the recent research advances in literature. For the application research, a good question may propose like: The original scheme is super powerful and applied everywhere, yet new application scenarios emerge and new requirements are imposed, so changes must be made to the original scheme in the context of new application scenarios. So you check the scheme to find the whereabouts to improve it and test the benchmark to prove that it improves in some meaningful way.

3. The third thing is to form a research proposal, and, inquire the experts in the field for their advice, get feedbacks and supports and form research teams. I was told that most research in UESTC is done in research groups. And there are more than 63 groups that could create income more than 10 million RMBs. So form the notion of doing research as a team. Share your research ambition with group members and potentially form various teams within a group. Aim big. Do not aim research projects that only fund several thousand RMBs.

Magi system is materializing in real world

Magi system is materializing in real world. I tried the Open AI and found it fantastically useful.  Some Gword company may be falling, even though the apparent evidence may take years to appear.

Some Chinese enterprise owners are concerned about the turmoil that is happening in the process of transferring to younger generations. Yet Microsoft is illustrating a somewhat to the point answer, that is to invest and occupy a company that is promising. Old companies will eventually pass by, as old products will finally do. By giving a hand in the growth of new products, new things, and of course young people, old power remains without the fear to be judged and justified.

For those Chinese companies, one thing is certain, a company is structured to best facilitate the delivery of a product or service. Thus a company will of course fade with the comparative shrink of the product. New organizations will take place with new structure that best suits the new product that is newly occupied. The new comer will inherit the brand though it is not the old one any longer. A company’s fate can not disconnect with the destiny of a nation. Only when a nation is creative enough can a single company escape the fate of falling by having as many alternatives to pick to occupy.

Apple is losing a string of designers

Apple is losing a string of designers [1]. Rumors have come that the designer department is restructured under operations one and that leads to the consequences. To be honest, I am not interested in apple products any more. The new iPhone and new Macbook models do not look as attractive as they were. The app store is still the must-have, and yes if I am gonna replace my handset it would still be another iPhone, but their products don’t deliver the magic anymore. The full consequences would take years to disclose.

Avoid using apostrophe u2019 when in Chinese systems, use u0027 instead

There is a severe issue in font displaying when it comes to presenting text with the symbol ’ (u2019, Unicode 2019). The problem is that Chinese text system uses exactly the same ’ (u2019) Unicode  symbol as the right part of ‘(u2018) ’ (u2019) pair. And ’ (u2019) is also common alternative apostrophe of ‘(u0027).  The issue is, while you can’t input that ’ (u2019) with standard American keyboard layout, MS word will by default replace that for you. So when you paste a paragraph of English text from MS word, and the text box on the webpage displays in Chinese font(such as the Song font), you will get several full length ’ (u2019) as wide as an ordinary Chinese text within a English paragraph of half length English texts. And when you change the font to English, it recovers from full length to half length again. So the issue comes from that Chinese fonts assuming all the ’ (u2019) symbols as the right part of the quote pair ‘(u2018) ’ (u2019), regardless of many cases in English such as “He’s a good professor”. Finally, it looks the way as “He' s a good professor” in Chinese font.(Just for illustration. Since it is displayed in English font, this symbol' is actually  U+FF07[1]. My point is, in Chinese font, the normal U+2019 ’ looks exactly the same as ' thereby displaying “He’s a good professor” as “He' s a good professor”.)

That’s super annoying. Better the new Unicode standard for  the Chinese typeset use another Unicode position for the  ‘(u2018) ’ (u2019) pair, and leave that ’ (u2019) as the only symbol used in English.

Couldn’t imagine

Couldn’t imagine academics in mainland China has developed so rapidly. An impulse – the covid 19 – which drives many good researchers back to China, has generated consecutive good academic changes in China.

Apple should refine its business strategy to reveal new chips

Apple is not doing so well in market achievements. I think it should refine its business strategy to reveal new chips. Before apple made his own M-series chips, it is Intel’s responsibility to deal with that. Intel is notorious for its slow improvements in chips [1]. Yet it is commercially beneficial to do it in a crawling way. Consumers do not anticipate a big increase when they already bought an older model. Any potential regret will stop them from buying the products at any time in the interim. When it comes to apple, he has to prove to the public that apple silicon is remarkably better than previous structures of CPUs, to prove that moving to the brand-new M-series CPU is worth all the costs and troubles. So the first performance bump is crucial, yet leaving less space and surprise for the second gen chip product. And all the consumers are holding their pockets to wait for the next generation coming to life, which is a bad situation for apple. So we see the plummet in market performance for apple this year in 2022, especially for Mac products. There are rumors everywhere about the new 3 nanometer M3 chip coming along from TSMC and every intelligent potential customer is just waiting.

That is a dilemma. Apple has to win the performance battle with Intel to prove to the industry that apple silicon chips are worth transferring to, meanwhile he has to slow down the steps to minimize the regret for consumers, especially when apple’s plans are highly visible to the world despite a strict term of confidentiality. Another tough situation for apple, apart from all the twists and turns in developing the chip itself.

Life is an ever-printing inkjet printer

Life is an ever-printing inkjet printer. One is finished whenever he stops his foot steps, just as the printhead clogs after idling away for few weeks. Roll out non-stop, or the actual life that truly lives conclude long before it comes to its physical destination.
