iSpiderman··on Show HN: An easy-to-use online curve fitting tool
Very nice. I will use this at school to quickly produce fits. File import does not seem to work though...
iSpiderman··on Show HN: From Criticism to Constructiveness
During the current Covid-19 situation, most people I talk to tend to criticize a wide variety of things.

I think it is helpful for us personally as well as for the whole human race if we transform criticism into constructive actions.

This morning I wrote a short text and setup a simple form in order to collect these possible transformations. If only every person reading this adds one entry we can come up with a simple and straight forward manual to make the world a better place (in tiny steps :)

iSpiderman··on Ask HN: How to self-study physics?
I discovered the post by Susan Fowler a few years ago and really liked it.

I studied physics (2001-2006) and teach physics (and math) at a high school and am working through the list of proposed books (and others [1]) again, just to stay up-to-date :)

Other ressources: brilliant.org, quanta magazine,youtube channels (Veritasium/Vsauce/Physics Girl/PBS Spacetime...), ...

[1] e.g. Leonard Susskind's "The theoretical minimum" series.

iSpiderman··on Ask HN: Physicists of HN, what are you working on these days?
I have a master's degree in theoretical physics (2006), first went into consulting. After two years I quit and implemented currency trading algorithms for a small company for five years. After that, I tried something on my own (not related to physics or coding) and slowly slithered into teaching.

Today I teach math and physics in high-school and feel like never having had a better job in my life.

iSpiderman··on My Salary Progression in Tech

I am shocked and surprised at the same time (knowing that I only selected quotes of a few commentators).

Shocked to see the same mindset as many managing consultants and investment bankers I have met and worked with. They work a lot with the idea to stop working eventually. Not a single one of them has retired early. Not a single one of them I would call happy or satisfied (again: my bubble).

“Man. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived.” - Dalai Lama

Surprised maybe because I hoped here on HN people might have a different mindset towards money and success. Or: know that there is not a strict connection between the two. To read all this "Keeping up with the Joneses" makes me sad...

Choose life, not career. Find something you love doing and do it for the 'work' itself, not for some postponed happiness.

iSpiderman··on Nobody Knows How to Learn a Language
0. use Quizlet's search to find large collections of vocabulary:

1. search for e.g. french (https://quizlet.com/subject/french-basic-vocabulary/)

2. look for the list(s) with the most words

3. check quality (if you can :)

4. copy them to your language directory

5. repeat

if you speak German, the addition of "Langenscheidt" could help...

Example (contains about 6000 words): https://quizlet.com/ThomasBisig/folders/franzosisch-wortscha...

iSpiderman··on Show HN: Scatterstocks – visualize the impact of news on stock prices
That's very nice.

About ten years ago I developed the 'Scale of Market Quakes' for FX data and wrote a paper [1] about it (it's terribly written!), which was then released as a web service (www.olsenscale.com, not available anymore) and journalists etc could sign up for.

The idea was to measure the turbulences released in the market by e.g. quantitative easing by the FED. Was a great project and I learnt a lot.
