Chapter 1 Introduction to Microbiology

Microbiology 197 - Chapter 1 lecture for class.

[sheryldeleon]

Dr. Jim, I just wanted to say thank you for being such an incredible teacher. I recently took an intro to microbiology online here at a community college and struggled immensely in the beginning. Although I found microbiology to be interesting, I did not get as much out of it until I found your lectures. I watched all your lecture videos with my studying. You made taking an online class much more enjoyable. I recently took my final and thank you for helping me get an A in this class!

Dear Mr. Kerschen

This video should have way more views and likes, it's the best quality class on youtube I have seen, thanks for your effort and time spent here, you are the best.

I start microbiology soon, and I want to get ahead! Thank you for doing this! I actually learned a lot!

Anyone from 2020? 😂😂 feeling relatable

iam watching YouTube to prepare myself for prerequisites for nursing school. school is in the fall and I just wanna feel like wow I know the answer to that and feel confident in passing my classes 😊 thanks

Hi Dr. Jim,
Just wanted to thank you for this great service you've provided! I'm a second time student, getting my pre reqs for nursing done and this is a lovely supplement to my online course.

Be Well!

THANK  YOU ! got a B this morning on my Excelsior Exam - self taught!!!!

[supersnowva]

Watching your videos for my final exams... please keep doing it. you are doing us students a great favour...

[FrozenSummerNight]

I'm preparing to be a lab doctor. Those lectures are really helpful. Thank you so much!

[XxAlexxX]

watched these videos before I even had MicroBiology lol thanks

[solsoul]

Wow thanks! My teacher doesn't include almost any writing with his power points so this is beyond helpful!

As for the Theory vs. Law concept, the way I think of it is this:

a) A theory is just any model one invents to compute predictions. The goodness of a theory is the same as the goodness of a model.
b) An *accepted* theory (accepted by the scientific majority) is one that has stood the test of peer review and criticism and won consensus.
c) As time goes on, theories either evolve or go extinct.
d) Humans have (possibly for the first time in the Universe) began an unusually transcendental evolution path that has allowed us to turn a curve and begin to develop at an exponential rate mentally. As a result, most of our big theories today are of the type that they will never be "disproven" because they imperically model very tightly within their given domain. They will only be expanded or adjusted. This is true of the Standard Model of Quantum Mechanics, of Chemistry, and of much of Microbiology by extension. To the extent the theory still has conjectures that are equally or better matched by other conjectures, it remains a theory.
e) A law is an observation, with minimum interpretation, and so free of any alternative conjectures for any of its parts. This is usually achieved through intentional vagueness and limited statements, which is the case in the Law of Gravity, which simply states, "there's this phenomenon, right? I mean, you all feel it. Let's call it something." The Law of Gravity is simply the part of the theory that tells you "there's this thing.." but not the part that tells you, "and here's the complete and total equation." Newton's equation for gravity got modified by Einstein later to improve it's accuracy over a greater domain. But it's still probably not complete. So that part is a theory and not a Law, per se. But the part that just says, "Let's call this thing we experience 'Gravity'" is free from refutability as it's merely the naming of a common, self-evident *Observation*.

Thank you so much for all of your uploads. I figured I would prepare ahead of time for my summer 260 course and came across your gold mine of a channel :)

[Nelliejc]

Thank you for your online lecture. I'm taking a hybrid microbiology class and she doesn't have any lecture options to study off of. You have explained everything perfectly. Again thank you!

[florencecathy]

I just started my micro biology class and the professor is so disorganized thank God I landed on this professor's lectures.

[lovely]

YouTube classes are so much better than these expensive online courses

[suhasthegoat]

I'm not yet taking a microbiology class, but I'm really interested in this subject, definitely when it comes to genetic engineering. So, thanks for uploading your overviews for your class's, I'm sure by watching these I'll gain a good amount of insight. <3

You can really tell you love what you’re teaching! Thanks for teaching those who want to learn.
