@MarkJCarney Physicist here. Canada is a clean energy powerhouse because of its nuclear and hydro energy technology. It's not beause of restrictions on fossil fuels, but despite restrictions on fossil fuels. For details, see my lecture on Canada's energy production: x.com/i/status/20547…

Canada is an energy superpower and we’re going to lead the world in sustainable energy. That’s why we introduced new measures to cut methane emissions – to drive innovation, bring down pollution, and make Canada more competitive in global energy markets.

Rumors of Canada's greenhouse gas emissions are greatly exaggerated. Canada produces about 1.4% of global emissions. If they dropped to 0, the world would still have 98.6% of emissions to deal with. See my lecture for details: youtu.be/2Mv9WTZF2Zw

@Math_files Mathematician here to explain. The joke is about a famous mathematical result: 1 + ½ + ¼ + ⅛ + ... = 2 Each term adds half the remaining distance to 2. The sum will progress infinitely closer to 2 but will never reach it. My lecture with the details: x.com/i/status/20547…

An infinite number of mathematicians walk into a bar. The first one orders a beer. The second one, half a beer. The third, a quarter of a beer. And so on... The bar man says "you're all idiots" and pours two beers.

My lecture on how an infinite series can have a finite sum. For example, why: 1 + ½ + ¼ + ⅛ + ... = 2 In more elegant words: How Infinite Can Fit in a Box Enjoy! youtu.be/jiCVb7D4yV0

If the woman specified that her 1st kid is a boy, then the chances the other is a girl is 50%. Same if she specified that the 2nd kid is a boy. But if she says "one of" the kids is a boy, it leaves 3 equally likely possibilities: BG GB BB 2 of those 3 include a girl, so the chances of the other kid being a girl is 2/3 = 67%. Now if she also specifies that the boy was born on Tuesday, it further restricts the possible cases, especially by rejecting all cases of girls without a Tuesday brother. This brings the probability of the other kid being a girl down to 51.85%.

@GLabsPlus @Math_files I don't understand; the boy and Tuesday are unrelated to the gender of the other kid. It should be 50% This is not a conditional probability. Putting two unrelated things in one question doesn't make one depend on the other.

Ordering a Pizza for Delivery 1995 – You call – You order in 2 minutes – It arrives in 30 minutes 2005 – You go to the website – You customize it – It arrives in 45 minutes 2026 – You download the app – You create an account with email verification – You add your address with a PIN on the map – The map can't find your street – You add it manually – You select a pizza – The ingredient you want has an extra charge – You add a card – Payment error – You pay with another method – "Your order will arrive in 85 to 140 minutes"

@Antikristos666 @Math_files Assuming there's an infinite number of names, the answer is 50%. In general, the probability is, 2n/(4n-1) where n is the number of categories for the extra information given. For day of the week, n=7 For month, n=12 For name, n=∞ n=∞ means: 4n-1=4n 2n/(4n-1)=2n/4n=0.5

@GLabsPlus @Math_files Mary has 2 children. She tells you that one is a boy named Jack. What's the probability the other child is a girl?

@KlausLadwig @Dawn_Devourer @Math_files Very similar. Also 3 options, one of which is 2 boys.

@GLabsPlus @Dawn_Devourer @Math_files So that would transpose to the Monty Hall problem ?

@Math_files Mathematician here. If k_sub_B and k_sub_R have opposite signs, then the solution to this system of differential equations is sinusoidal: R(t) = Asin(ωt) + Bcos(ωt) B(t) = Csin(ωt) + Dcos(ωt) The relationship fluctuates between ups and downs but is stable. No growth or decay.

You’re single and there’s a knock on your door. Your blind date arrives and they’re incredibly attractive, the kind that instantly raises your expectations for a perfect evening. But then you notice something unusual on their arm, a set of mathematical formulas tattooed neatly. You don’t need to fully understand them to catch the hidden message. They describe a strange dynamic where the more one person gives, the more the other loses, and the more the other gives, the more the first one fades. It’s a loop where instead of growing together, both slowly drain each other over time. In simple terms, it’s a relationship that cancels itself out. So while everything looks exciting at first glance, the math quietly warns you that this might not end well. The real question is, do you ignore the signs and go ahead with the date, or trust the logic and save yourself from a story that’s already headed toward zero.

Remember: Probability is the portion of a specific set of events that meets a particular criteria. Additional information can change what set of events we know we're dealing with, which can change the portion that meets the criteria.

If Rush Hour 4 really is one of the subjects to be addressed at the Trump Xi summit in China, along with major economic and geopolitical issues, it shows how important film is to culture. Some say a nation's power is a combination of military, economic, and cultural might.

If she didn't mention Tuesday, the probability that the other child is a girl would be 67% as suggested in the 1st picture. The information about day of the week, or time of day, changes the constraints for the population that the woman is sampled from, which changes the probability.

@GLabsPlus @Math_files If she didn't mention Tuesday, would the probability change? What if she also mentioned time, like at 2 o clock

@AllotErwan @Math_files Why do you say that?

@GLabsPlus @Math_files yeah, but the good answer is 50%

@AllotErwan @Math_files 50% is approximately 51.85%. Pretty close.

@GLabsPlus @Math_files don't agree, for me it's 50%

@Variety Ok, who would have guessed that one of the goals of the Trump delegation's visit to China was to scout locations for Rush Hour 4? Meeting agenda: Ukraine Russia Taiwan Iran Strait of Hormuz Starlink Tariffs Rush Hour 4 Oil Prices

“Rush Hour 4” director Brett Ratner is reportedly joining Donald Trump on his visit to China in order to scout locations for the new movie in the Jackie Chan-Chris Tucker franchise. The “Rush Hour” franchise is said to be a favorite of Trump’s, with the president reportedly personally requesting that Paramount revive the series for a fourth movie. variety.com/2026/film/news…

@Clint_Davey1 The Empire massacred the Jawa caravan and killed Luke's aunt and uncle at the start of the first film. Darth Vader chokes someone nearly to death just for disagreeing with him. All that before blowing up Alderaan... And then they blew up Alderaan just to show off their weapon.

You only know the Empire are the bad guys because of the British accents and ominous music.

@FoodProfessor During the Chicken Sandwich Wars, circa 2020, between Chick-fil-A, Marry Browns, Popeyes, and KFC, consumers won. Competition makes companies try harder and do better. May the coming Donut Wars between Dunkin' Donuts and Tim Hortons produce similar positive results.

@draftnbyu1 @Kalshi_Culture I see your point. Perhaps one thing the sequel trilogy did right was having Yoda as a puppet instead of CGI. That said, Yoda fighting in the prequel trilogy might not have been possible without CGI.

@GLabsPlus @Kalshi_Culture Yes, in the older movies they what is called practical effects. Honestly for me, any Star Wars movie or show should use these. That's what gives it its Star Wars look. Excessive CGI looks weird in the SW universe

These visual effects are 41 years old and they still blow our minds. “The Return of the Jedi” (1983)

@Math_files This is a varriant of a famous probability puzzle often called the Two Daughters riddle. I have a video lecture specifically on that riddle, which many probability puzzles are based on Here's the link: x.com/i/status/20545…

@Math_files The chart below helps explain things. It shows all 27 possible cases of at least one Tuesday boy in white. 14 of them include a girl. The two left most columns are the 1st kid, and the top two rows are the 2nd kid. Each white or Grey cell is a possible combination of 2 kids. 🧵
