This means that any particle that contains a strange quark can not decay due to strong force (or electromagnetism), but instead with the much slower weak force. What makes strange quarks different from down quarks–apart from having 25 times the mass of down quarks–is that they have something that scientists call "strangeness." Strangeness is basically a resistance to decay against strong force and electromagnetism. Like all fermions (which are particles that can not exist in the same place at the same time), strange quarks have a spin of 1/2. Like down quarks, strange quarks have a charge of -1/3.
Strange quarks are the third lightest quarks, which are subatomic particles that are so small, they are believed to be the fundamental particles, and not further divisible.

Install the Python Selenium package via pip install selenium.Download der corresponding ChromeDriver from here for your main version and put the executable into an accessible location (I use Desktop/Scraping).90 (my main version is thus 77, the number before the first dot). Typically found by clicking About Google Chrome. Install Google Chrome (skip if its already installed).In case you want to use another Browser (e.g., Headless) you will have to download the respective WebDriver. I will outline the installation and usage of Selenium with Google Chrome. Unfortunately, a little bit of preparation is required beforehand. Let’s look at an example to illustrate the usage of Selenium. However, Selenium is equally powerful when it comes to automating repetitive web-based tasks. The initial idea behind Selenium, as far as I know, is automated testing. In layman’s term, selenium pretends to be a real user, it opens the browser, “moves” the cursor around and clicks buttons if you tell it to do so. Selenium can be used to automate web browser interaction with Python (also other languages). Most of the time, however, you will have to go through the steps of clicking buttons, scrolling pages, waiting for loads and all of that … or at least you have to make the webpage think you are doing all of that. In which case, it might be possible to directly access the API and fetch the resulting data without having to go through the unnecessary steps in-between. Sometimes the user action might trigger a call to an exposed backend API. Because this happens only after specific user interactions, there are few options when it comes to scraping the data (as those actions do have to take place). The concept of “single-page application” means that the web page itself will change without the user having to reload or getting redirected from page to page all the time. However, most modern web pages are quite interactive.
