I was reading about Carl Sagan...well actually more about this... please log in to view this image and I noted Carl had an IQ of 170, so then I googled who had the highest recorded IQ ever, well depends how it's done, so it's debatable but that aside the answer in the Guinness Book of Records is... Marilyn vos Savant (/ˌvɒs səˈvɑːnt/ VOSS sə-VAHNT; born Marilyn Mach; August 11, 1946) is an American magazine columnist who has the highest recorded intelligence quotient (IQ) in the Guinness Book of Records, a competitive category the publication has since retired. Since 1986, she has written "Ask Marilyn", a Parade magazine Sunday column wherein she solves puzzles and answers questions on various subjects, and which popularized the Monty Hall problem in 1990. https://en.wikipedia.org/wiki/Marilyn_vos_Savant https://en.wikipedia.org/wiki/Monty_Hall_problem Savant's response was that the contestant should switch to the other door.[3] By the standard assumptions, the switching strategy has a 2/3 probability of winning the car, while the strategy of keeping the initial choice has only a 1/3 probability. When the player first makes their choice, there is a 2/3 chance that the car is behind one of the doors not chosen. This probability does not change after the host reveals a goat behind one of the unchosen doors. When the host provides information about the two unchosen doors (revealing that one of them does not have the car behind it), the 2/3 chance of the car being behind one of the unchosen doors rests on the unchosen and unrevealed door, as opposed to the 1/3 chance of the car being behind the door the contestant chose initially. The given probabilities depend on specific assumptions about how the host and contestant choose their doors. An important insight is that, with these standard conditions, there is more information about doors 2 and 3 than was available at the beginning of the game when door 1 was chosen by the player: the host's action adds value to the door not eliminated, but not to the one chosen by the contestant originally. Another insight is that switching doors is a different action from choosing between the two remaining doors at random, as the former action uses the previous information and the latter does not. Other possible behaviors of the host than the one described can reveal different additional information, or none at all, leading to different probabilities. In her response, Savant states: Suppose there are a million doors, and you pick door #1. Then the host, who knows what’s behind the doors and will always avoid the one with the prize, opens them all except door #777,777. You’d switch to that door pretty fast, wouldn’t you? Edit: Oh I forgot to say, her IQ was 228 btw.
I'm only focusing on the last question here at 36 mins, hopefully the video will start at that point. Chuck Nice's response about aliens had me in tears, love the way they approach teaching...
Twitter can see decent stuff posted sometimes... Fetal development!! *Week 1-2: Implantation and Embryogenesis* 1. _Fertilization_: A sperm fertilizes an egg, forming a zygote. 2. _Implantation_: The zygote implants in the uterine lining, beginning embryogenesis. *Week 3-8: Organogenesis* 3. _Heartbeat_: The heart begins beating around week 6. 4. _Major Organs_: The brain, lungs, liver, and kidneys start developing. 5. _Limbs and Digits_: Arms, legs, hands, and feet begin forming. *Week 9-12: Sensory Development* 6. _Eye Formation_: Eyes develop, and eyelids fuse shut. 7. _Ear Development_: Ears form, and the auditory nerve connects to the brain. 8. _Taste and Smell_: Taste buds and olfactory receptors develop. *Week 13-16: Motor Skill Development* 9. _Muscle Movement_: Muscles develop, and the fetus starts moving. 10. _Swallowing and Kicking_: The fetus practices swallowing and kicking. *Week 17-20: Sensory Refinement* 11. _Skin and Fat Layers_: Skin and fat layers form, regulating body temperature. 12. _Hearing and Vision_: The fetus can detect sounds and light. *Week 21-24: Brain and Lung Development* 13. _Brain Wave Activity_: Brain wave activity increases, indicating cognitive development. 14. _Lung Maturation_: Lungs start producing surfactant, preparing for breathing. *Week 25-28: Preparation for Birth* 15. _Pancreas Function_: The pancreas starts producing digestive enzymes. 16. _Immune System Development_: The immune system matures, preparing for life outside. *Week 29-38: Final Preparations* 17. _Fat Layer Accumulation_: The fetus accumulates fat layers, preparing for energy needs. 18. _Lung Expansion_: Lungs expand, preparing for breathing. *Week 39-40: Birth* 19. _Full-Term_: The fetus is fully developed and ready for birth. 20. _Birth_: The miracle of birth occurs, marking the beginning of a new life.
Big fan of Carl Sagan. He used to explain things in a really user friendly way. The world needs more people like him coz twitter and the like is awash with charlatans and half baked conspiracy theorists.
Whatever happened to Johnny Ball ? I used to love seeing him on the tele as a kid. He was another one who’d explain maths and science in a really engaging and fun way. These are the people I want to see on social media. Johnny Ball, Neil DeGrasse Tyson, Mick West, Brian Cox. Not some ****wit tik tok influencers chatting ****e about chemtrails and HAARP.
Could be space junk, there's loads of it up there. Especially if it's from a low level satellite, it could have re-entered the earth's atmosphere at an angle where it didn't burn up, but was 'red hot 'when it hit the ground.
It is space junk, it obviously is there's no could be about it lol. Already several ideas of what item it has come off, ie rocket seperation ring and a few other ideas.
