I'm designing something and part of it has a aluminum block that will be have a M6 threaded hole. I want to add a nylon washer to give it a stop nut or lock nut type of feature. I'm looking for input into the appropriate diameter and dimensions of the washer. also I'm wondering if there are any...
I’m going to talk about two of the first science experiments in recorded history. One was allegedly performed by the Prophet Elijah in Israel in the 800s BC [1], the other by the Pharaoh Psammetichus in Egypt in the 600s BC …
From Physics Forum:
In the biblical account, Ahab and Jezebel had established the worship of the god Baal. Elijah, believing his god to be the true one, proposed a controlled study to find out which of the two was the correct god to worship. The priests of Baal would prepare a bull for sacrifice and leave it on their altar, and Elijah would leave a bull on his altar, and they would see which one spontaneously caught on fire. The experimental protocol and its results are discussed in 1 Kings, chapter 18, but to summarize, the sacrifice to Baal was left unburnt, while Elijah covered the wood below his bull with water and it still caught on fire. This allowed the Israelists to know which god they should be worship, and subsequently all the priests of Baal were taken down to the river and murdered.
This study has a number of methodological flaws. The same protocol was not followed for each sacrifice, and priests only gathered a single data point and neglected the possibility that a god was choosing an altar to burn at random. Any attempts at replication were hindered by the murder of the Baal camp, and that is generally frowned upon in scientific circles.
hi. i sent you an email about a physics problem i am having, but i have not received a reply yet. my email has been reported as having problems, so i am wondering if you received my email? you are one of my favourite youtubers and i am very thankful for your videos. xx
Dear Anon,
I haven't received such an email. I should also add that unfortunately, I don't have time to be a physics tutor, though I'm really glad that you're enjoying The Physics Factor and that you are engaging with physics. If you don't have anyone to help you in-person with physics, I suggest poking around/using Physics Forums, an online community for physics and math help.
Good luck!Katie
