There is a mistake at 32:08, 107 x 0.51839 = 55.46773; and that's how you get the correct answer 107.97

I an over 70, and cannot see very well, but I can hear and then write. However. when the teacher says ºThen we put this here. and that there" I have no idea of what THIS and THAT and HERE and THERE are. I am lost and cannot take correct notes. If. on the other hand, the teacher says "We put SECONDS in the NUMERATOR. and we place the number 1609 in the DENOMINATOR, , then everything becomes clear.

The teacher is actually doing a very good job, but the power points (or whatever medium is used), while they may be sufficiently large in the physical classroom, become miniscule when they come across a Youtube screen. I am not writing this to criticize the current course -- which I applaud and for which I thank you from the bottom of my heart (this is great. high quality FREE education -- like it can be in an ideal world); I am writing this as, I hope, a guide which will help make this type of class even better the future. Thank you so much!

Damn this lecture covered like 3/8's of my high school Chemistry class lol

[thereal_johnle]

I learned more here than in a semester

[enoching]

i think some of the math is wrong? .51839 x 107 = 55.46773, which then leads to the the right answer she wrote down for adding the averages together.

[Bloodshaded]

She gets the first answer by 1255 x (3600/1609.3) = 2807; going to 4 sig figs from 2807.4318 for anyone else who was totally lost like me

Great lecture. Concise, digestable, more than makes up for a year of 'lessons' from my deadbeat chem teacher

[SC-qrfh]

Thank you for helping me prepare for my upcoming chem 1a course this summer

[Motosfourlife]

Thanks really appreciate this kind of lecture. No history, no stories, no bs straight to the point.

I am studying Chemistry because it is amazing branch of science because I love to understand how does the universe work.

Doctor Brindley,

It has come to my attention that I believe there is a mistake on the powerpoint slide at 43:39. On the fluoride (F) at the farmost left, there are 6 valence electrons when there should be 7.

Much as I'm trying to love chemistry, I AM SO LOST RN!

[carlosmartinez-wxzy]

I'm just amazed that no one raised their hands.

[obadiyah]

It would have been helpfull if she explained WHY the intro math is significant and why one will need to care about such details for chem. Without this proper roadmaping students will spend too much mental energy guessing at the end point of all of it, and that mental churning takes away from understanding the details.

[darellw.]

She does not explain the math computations for the questions after canceling seconds and meters this is where the student gets lost...

[purplecircle]

Now this is how you organize a chem lecture. Good fuckin job uci

[theolerios]

Brushing up on Chemistry before taking it at college, any suggestions for a good textbook?

[brainstormingsharing]

Absolutely well done and definitely keep it up!!! 👍👍👍👍👍👍

93, 000, 000*(1609.3/300, 000, 000)=498.883 seconds => 8.31 min

Hi guys! Im currently in Grade 12 and taking Chem. My grade at the moment is a 95. What I've recently been doing is when I have some extra time, ill go and watch these lectures and take note on what I'm learning so I can prepare for University next year. Do you guys think this is a good idea or should I not do this?
