Push-up workouts are indispensable for academic career

Recently, I found that building a habit of push-ups is essential for a sustainable academic career. Keep the strength in waist will help one to sit straight and minimize energy loss coming out of  a bad sitting posture. From the word of a health advisor in Harvard [1], it is impossible to maintain the subtlety of being able to maintain the body in ideal postures without a basic amount of core strength. Even for workout of push-ups, it is by no means possible to do in standard position without a certain period of training time. And it is still worthy to keep going with bad position, just to turn the basic core strength into reality.

PS: This way of workout applies in many other fields.

Benefits of latex

Benefits of latex

  1. Get rid of slow response for long articles.
  2. Fast input for greek symbols and math sympols.
  3. Free from the pain of submitting another journal.
  4. Facilitates manuscript preparation on a Mac.

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.

Chinese market is getting rid of pirate software

Chinese market is getting rid of pirate software. Usage with license is more prevailing nowadays. The legislation for software patent is ripe in China. Many software vendors are quietly distributing pirate software packages on the Internet that is actually released by the official themselves, increasing usage ratio and user coverage in China, leading users to accept their format of file, and suing those companies and research institutions which do not buy a(enough) legal copy(copies). That is a great strategy since 20% of the wealthy institutions will contribute to 80% of the revenue. Making the software de facto free to 80% of the individual users will help make the money from the 20% richest buyers and it can also prevent a competitor from emerging in China.

Apple computer is much more appealing for researchers in Math, Physics, CS

Apple computer is much more appealing for researchers in Math, Physics, CS. Once you compose your paper in English and Latex, you won’t need Word or Powerpoint or NoteExpress or Zotero. As long as your printer supports the mac OS system, it will be of no pain to switch to the Mac platform.

transform path illustrates below:

MS Word     ->Latex

Powerpoint->Latex Beamer

NoteExpress, Zotero->Bibtex

Others:

Excel->LibreOffice

Mail: Mozilla Thunderbird

Calendar: So many options out there

C compiler: Mac has its back-end clang for its use.

 

Hard core crafts

One must acquire some sort of hard core crafts to be financially independent. It may be a CPA certificate which proves your ability to audit business transactions, a scholarly technique to accommodate oneself in a college, the computer science knowledge and experience to find a job in big tech companies. The craftship has to be independent of the penetration of capital, to ensure a sound living in any case.

The internet and technology upgrade has taken many people out of their jobs. Basically, there are two kinds of job, inventing stuff and selling stuff. And the Internet and easy-to-use applications on the phone has taken jobs away from customer-end salesman. Customers can search everything on the Internet with a phone and the information about products is no longer a privilege to the salesman. With that change going on, one has to learn to do the really tough tasks for computers to deal with to get himself into the payroll. For example, the chatGPT is taking jobs away from programmers, especially those who only programs to configure the framework (such as the Java spring framework). Those who delve into the black box and know how things are made up with are intact from the threat of chatGPT, as they acquire a solid understanding of modelling things.

Benefits of maintaining spontaneity

Benefits of maintaining spontaneity includes:

  1. Noise resistant in listening.
  2. Accent tolerant in listening.
  3. Low brain power consumption in grasping what you have listened or what you have read. That is, you will understand with little attention paid when very tired and grasp the notions faster when reading an academic paper.
  4. Spontaneity is intensifying itself. The longer you keep, the higher the extent you achieve. That will make your expression easier than the painful intentional ones who force themselves to speak in English. The latter guys always feel painful and won’t last long.
  5. Once I have acquired spontaneity, I can’t afford to lose it. Revising an academic paper is blazingly fast and I could not possibly imagine how long would it take without it.
