Welcome to Brazilian Carnival, 1955 style, in Rio de Janeiro in the 1950s. 60 years ago, perhaps, when your grandparents were kids. That's a long time, or maybe the blink of an eye? They say that the more things change, the more they stay the same. Watch the video. What do you think?
With beautiful images of Rio De Janeiro, a Pan American four engine clipper landing at the airport, passengers leaving the plane, President Vargas exiting a limousine, crowded streets, people dancing and singing to Samba bands, people in costumes and masks, dancing groups, individuals, beautifully costumed people, and children watching...
The technological singularity is the hypothesis that the invention of artificial superintelligence will accelerate technology, causing incredible, unbelievable changes to civilization.
These tenses will be helpful... if you have a time machine. Enjoy the show !! Howard Wait, hold on. Pause.

Howard Something doesn’t make sense. Look. In 2015 Biff steals the Sports Almanac and takes the time machine back to 1955 to give it to his younger self. But as soon as he does that he changes the future, so the 2015 he returns to would be a different 2015. Not the 2015 that Marty and Doc were in.
Leonard This is Hot Tub Time Machine all over again. Look. If future Biff goes back to 2015 right after he gives young Biff the Almanac, he could get back to the 2015 with Marty and Doc in it. Because it wasn’t until his 21st birthday that 1955 Biff placed his first bet.
Sheldon But whoa, whoa. Is placed right?
Leonard What do you mean?
Sheldon Is placed the right tense for something that would’ve happened in the future of a past that was affected by something from the future?
Leonard [thinks] Had will have placed?
Sheldon That’s my boy.
Leonard OK. So, it wasn’t until his 21st birthday that Biff had will have placed his first bet and made his millions. That’s when he alters the timeline.
Sheldon But he had will haven’t placed it.
Howard What?
Sheldon Unlike Hot Tub Time Machine, this couldn’t be more simple. [laugh track] When Biff gets the Almanac in 1955, the alternate future he creates isn’t the one in which Marty and Doc Brown ever used the time machine to travel to 2015. Therefore, in the new timeline, Marty and Doc never brought the time machine.
Leonard Wait, wait, wait. Is brought right?
Sheldon [thinks] Marty and Doc never had have had brought?
Leonard I don’t know, you did it to me.
Sheldon I’m going with it. Marty and Doc never had have had brought the time machine to 2015. That means 2015 Biff could also not had have had brought the Almanac to 1955 Biff. Therefore, the timeline in which 1955 Biff gets the Almanac is also the timeline in which 1955 Biff never gets the Almanac and not just never gets: never have, never hasn’t, never had have hasn’t.
