🇮🇱 Netanyahu went full edgelord: "Jesus Christ has no advantage over Genghis Khan. Because if you are strong enough, ruthless enough, powerful enough, evil will overcome good." Bro… that’s not a flex, that’s a facepalm on steroids. Israel’s already fighting the global optics war, and the PM decides to drop “might makes right, Jesus who?” in the middle of it. PR team must be screaming into pillows right now. Source: @disclosetv

The double slit experiment is the probably most misunderstood experiment ever. I have no idea who created the myth that if you 'look' at one of the slits, then the particles (photons/electrons) stop behaving as waves. It's wrong! They of course STILL behave as waves! Because particles are also waves, always. Photons and electrons make a self-interference EVEN ON A SINGLE slit. Don't believe it? Below an actual measurement from a laser diffracting on a single/double slit from Wikipedia. What happens if you measure which slit the particle goes through is that you get no interference between BOTH slits. And no, you don't need a conscious observer for this. Believe it or not, there have actually been experiments where they had people literally look at a double slit to see if that makes any difference and the answer is no, it does not. The entire mystery of the double slit is in the path of the particle TO the double slit. Because it seems that the particle must "know" whether it WILL be measured at one of the slits before it even gets there. It must "know" whether to go through both or just pick one. Seems like the future influences the past? Not really, it just means you have a consistency condition on the time evolution.










“The things that people are saying about the rationale for this conflict are not true,” says @KonstantinKisin. “I do not believe that Iran was about to pose a threat to the United States… Currently, as I sit here, I don't understand the strategy… I am seriously concerned this will drag on... I’m struggling to see how this ends well at this point.”
