After very long research Adguard and 1 Blocker are the best adblockers for iOS . <| sep |> It has pokerus btw so be sure to spread it <| sep |> If you are just starting an undergraduate program , the best approximation of your chance of ending up as a professor is zero . Look at the numbers . A professor at a research university can train at least one or two graduate students each year . Over the course of that career , that creates 3060 replacements , but heshe only retires once . Physics departments are not expanding very much . And even if you do somehow work hard , get the grades and recommendations along the way to get into a good grad school and a good postdoc and a good tenure track position , you will find that getting tenure does things like break up marriages . And you are not on an Elysian Field of imagination , you have to work hard to find money for your research from governments that don ' t care about your happiness . It is OK to love physics and be excited about it . But you should get realistic about your career plans earlier rather than later .
