In 3 minutes and 40 seconds you explained this better than my high school math teacher could've done in months back in the day. Just speaks volumes of your competency or her incompetency. I needed closure, thank you.
@@jursamaj naaahh, I left out that part because I wasn't a problem. The whole class struggled to understand wtf the teacher was talking about, and we were in a math high school (Second Gymnasium in Sarajevo). The other teachers adopted this with ease. Now there's no way anyone could tell me that 32 people didn't understand anything because it was their fault. Not a single one. If there were 3 of us who got it I would admit that it was due to my incompetence.
c^p == true only when c == true and p == true. If both are false, then c^p is false. "AND" doesn't check to see if both values are equal to one another, it checks to see if both values are true.
This is not what a Tautology is. For example “1 > 0 implies 0 > -1” is always true but not a tautology since if we replace “0 > -1” with “0 > 0” the result is false.
There should be new cathegories in Nobel prize. A) Quantum Phisics and phisics of atomic scale B) Phisics of Space and Time not be confused with spacetime C) Engineering That is hard risky choice but hursh shot.
from natural sciences perspective a dog is a dog but the word 'mammal' refers to a set that includes set of dogs. while mathematics and other human languages tend to define things via hierarchies, in the material world things are collections of simpler things (unless you are an idealist).
What about logical contradictions that are self-resolving? Self-resolving contradictions are tautologies too. Ex: the universe stays the same/the universe changes. Those are both true contradictions.
The universe stays the same is a contradiction because its expanding. It's not true. The other is a tautology because the universe is indeed always changing because of expansion. Its not a contradiction
Sure, but he's obviously a specialist. It's OK. The good news is the we still *know* what he means. Most linguistic fails are more about style than meaning.
You are incorrect. A hot dog is a mammal. It is made from parts of a cow, pig, or bird meat and organs made into a thick liquid and squeezed into a tube shaped casing, also made from mammal parts. At least one thing I said was true. So wouldn’t that make me correct on saying you’re not?Tasty for sure! Nathan’s famous is my go to 😂

@@birdboigenius6767 sure did, it was the very first high school math lesson actually

Funny how you leave out a 3rd possibility: *you* were the problem.

A tautology is always a tautology.
And a contradiction is always a contradiction
@@DrTrefor exactly lol
And this is a tautology too.
It is what it is. It is = It is.
It is it
always remember: he had to learn how to write backwards for us
thank you for the lesson sir
I'm pretty sure he just does it his way, then flips the video ... kol

Just gotta say, that setup you got for your classes/tutorials is amazing. Mayor respects!
Man, a thumbs of from the mayor! This guy is moving up in the world! ;) (jk of course)
0:42 “irregardless?” Ain’t no such animal. No sireee
I got up to around 0:43 when he said "irregardless" and my brain just couldn't take it. Had to leave. Lol
@@DrTrefor I hope the "lol" at the end successfully conveyed my jest to you and anyone else. ;) I finished the video and enjoyed it. :)
Yup, lost me at "irregardless".😂
My dawg/home Boi is a duck so..
I wonder why my professors are here for.
your tutorials are amazing. Thank you
exactly fml
The "It is what it is" phenomena is thick right now.
just realized that he writes inversely
Teaching style is so good,i try to understand & also teacher is so Handsome,,,
not creepy at all there bro
@Anthony The Invincible Iron Man Stark
😂😂
I can't thank you enough for these videos! :)
Where aren’t professors like this 😂
t - tautology, c - Contradiction
Tautology - always true
Contradiction - always false
Hey I've got a doubt, but c^p when c is always false and p is false will be true right? You've written that it will be false.
2:50
c^p == true only when c == true and p == true.
If both are false, then c^p is false.
"AND" doesn't check to see if both values are equal to one another, it checks to see if both values are true.
You are just from saving me😢
Thank you sm I couldn’t understand what my professor was teaching me
Please name your videos starting with serial numbers. While studying i wont miss any videosin the middle. I like your videos!!! Thank you!!!
You can just make a playlist. Changing every video title to have a number in front of it would not be feasible or really good for anything.
These videos are great. Thanks so much!!
Dr. Trefor Bazett is the GOAT.
Thank you so much Dr! now everything is clear😍
Although I can't understand fully British or American English but it was great explanation nd could be understood❤❤
IRREGARDLESS ‼️
This is not what a Tautology is. For example “1 > 0 implies 0 > -1” is always true but not a tautology since if we replace “0 > -1” with “0 > 0” the result is false.
Exactly! I’m a little reassured that I’m not the only one thinking that’s not what a Tautology is. But why did no one else point it out?
@@Eyenn_n glad you noticed too (:
Great explanations.

Very good explanation by you.... thanks a lot Brother
What sorcery is this, you can write mirrored!
What if when we apply t ^ q and c v q ?
Could you explain it for me, you had 3 years to figure it out

thanks Marc Gasol
Nice video ..from india
Regardless. Irregardless is not a word. 😊
THANK YOU SO MUCH
thank you so much sir!
Why do I need to learn this?
I feel like this should be an english class..
honestly asking, not trying to be condescending
Main argument is that logical thinking is important for lots of things. Diving deep on FORMAL logical arguments helps your logical thinking over time.
To understand bad arguments.
@@DrTrefor I can get behind that thanks!
what if the dog is a boston dynamics robot and not a mammal?
wait is he writing on a glass? how can we not see the glass???
thank you
Pls sir,why is the contradiction c^p and not cvp
What is Contingency?
Thanks a lot
irregardless? really?
can you tell me how to figure out what these are tilde D wedge B and tilde parentheses D tilde B prentheses? and how to know the order of operations?
Did he say anything after the "irregardless?" I clicked off after that.
Falfalogy is a statement that is always false, we denote this with the letter f XD (this is joke, but I'm sure I'll learn the word shortly)
Oh so contradictions are always false, see if I watched the whole video or read the title, this video would have 2 less comments
The use of "irregardless" has me deeply questioning the authority of this video.
It gave me pause as well, but a bit of research shows that it is in fact a word. I was always taught never to use it though.
Sure, but he's obviously a specialist. It's OK. The good news is the we still *know* what he means. Most linguistic fails are more about style than meaning.
Irregardless is a term
2:16 my man just make a cp joke?
He knows what that means on the internet?
T ^ P ??
Concise and engaging, thank you sir!!! : )
U didnt include contingency
What if its T and F? Then it's not Tautology and Contradiction
"Irregardless" 😂
This is a sentence, That is a tautology.
"irregardless" is a tautology.

I just came here because Kyon from “The melancholy of Haruhi Suzumiya” mentioned this.
DOES NO ONE REALISE THAT HE IS TO WRITE EVERYTHING LATERALLY INVERTED OMG
haha either that or I flip it on my computer:D
@@DrTrefor writing inverted is cooler so we'll go with that.

I was enjoying this until he say "irregardless". It's regardless !!!
It’s a word but it’s not fashionable and you should use regardless.
Dude has a PhD. I'm fairly certain that he's earned the right to use a word that is gramatically equivalent to its more handsome brother.
Imagine someone getting afended because you said a dog is a mammal lol
WRONG! a Hot Dog is not a mammal.pretty tasty though !
You are incorrect. A hot dog is a mammal. It is made from parts of a cow, pig, or bird meat and organs made into a thick liquid and squeezed into a tube shaped casing, also made from mammal parts.
