This. More people should be like you. On that note, I hate how rude most people on 4chan are. Like guys there's no point. Being friendly gets you way ahead in life, makes you feel better about yourself, and makes other people feel better at the same time—and it takes so little effort for such a huge return. Most arguments here are just pointless anger masked as a debate. Seeking first to understand your opponent is the first step you should take when making an argument, but you rarely see that here. Learning how to interact with people effectively is a part of being intelligent, but strangely it's the most disregarded thing here.

This biannual publication provides a set of indicators that reflect the level and structure of the efforts undertaken by OECD member countries and seven non-member economies (Argentina, People’s Republic of China, Romania, Russian Federation, Singapore, South Africa, Chinese Taipei) in the field of science and technology. These data include final or provisional results as well as forecasts established by government authorities.
The indicators cover the resources devoted to research and development, patent families, technology balance of payments and international trade in R&D-intensive industries. Also presented are the underlying economic series used to calculate these indicators. Series are presented for a reference year and for the last six years for which data are available.

What kind of math do you need to do to determine how fast the blade needs to rotate around its axis to cut a certain length of pasta?

I'm a mathlet but supposedly you guys know your shit to some degree so it would be cool to know an answer.

>>9363432
You set it to tree fiddy and then adjust until the length is just about right. There's no need to involve any math and it won't help much you since the extrusion speed varies slightly all the time depending on many things you can't keep track of in real time anyways.

Even if i assume this to be hyperbole is still beyond fucking retarded. The technologies and systems developed and constructed by the public over the past 60 years, particularly in infrastructure, are largely responsible for modern civilization.
>>
>>9367234
Maybe there's some kind of invisible psychological barrier because in the United States, good governance and useful public construction USED to exist but doesn't anymore.

Like how we built a railroad from New York to San Francisco 150 years ago. It took six years and cost $1.7 billion in inflation-adjusted dollars.

Today, we're eight years and $3 billion into a railroad from Los Angeles to San Francisco and it's nowhere near done although it's estimated that they might finish the job if given another nine years and $4.7 billion.

Space Planes that take off like a jet, and reach LEO, have been planned since the 1970's. You could do it with off the shelf tech right now.

Wont happen. Elites want space to be very expensive, no clue why. Best guess, to keep retards out of space. Space planes would be Very Cheap.

Google project Star Raker. And costs for payload, compared with current costs.

this idiot was posting this on Biz claiming he already had this PhD and this salary, came in here to try and get a confirmation.

no tard, you arent getting 300 grand just cause you have a math PhD.

so how du i interpret this /sci/ ?
intercept is my alpha so can i say it is significantly negative ?
did they ran a two tailed or a one tailed test ?
so if i use corrected standard errors and do this again with a two tailed p test
does it tell me my value is -0,4111 to a 99% significance ?

really need your help since im fucked if my interpretation is wrong

Hello /sci/. I am interested in starting a youtube series explaining the mathematical fundamentals of quantum walks and discrete quantum mechanical systems. I already have a youtube channel with simulations of these systems with no context:

https://www.youtube.com/watch?v=oA3bsl9oCBE

The issue is that I have zero experience with making these kinds of videos. Do you have any advice on what kinds of set ups work best? I want to make these videos about 3 minutes each so that engagement is high throughout the video.

The natural numbers don't contain imaginary numbers, is that why the natural number set is smaller than the rational set?
