  • In terms of performance, a K&N is the way to go, but if you’re looking for reliability, the regular old paper filters are better for your engine. They’re a much finer filter medium and catch a lot more dirt than a K&N will. Also the price difference is negligible, a paper filter is usually around 15-20, while a K&N is closer to $50 or $60 plus the future $30 or so for a recharge kit to clean and re-oil it.

    When it comes to oil changes however you’ve definitely got the right idea, cheaper with better oil and better filters. Also I do know that K&N uses a finer mesh in their oil filters than most compettitiors, so its worth it there.


  • NASAs budget in 2021 was $25b, but their economic output was $71.2b. NASA actually puts more into the economy than it takes to run. Between providing nearly 340,000 jobs and leasing patents on materials and technology developed in house, NASA more than pays their own way. Not to mention all the advancements in material science, medical technology, and engineering that they provide. NASA is well worth the investment we put into it, and IMO deserves much more.






  • That’s the cool part about chemistry, when used in this synthesis the dichloromethane becomes a whole new (presumably safe, but we’ll see what further testing turns up) molecule. Sodium is explosive and Chlorine is highly corrosive, but combine them and you get regular old table salt. Just because a reagent is dangerous doesn’t mean the products it creates will be.

    Edit: I just did a little research and it looks like 3,3′-Diindolylmethane (DIM) is safe for human consumption. It’s already sold as a dietary supplement. It’s marketed to help with metabolism of estrogens but we all know how “trustworthy” the dietary supplement market is.
