no teacher today, so we had to read things on our own.
louis pasteur was a french chemist who studied the shape of organic crystals. he discovered that diseases were caused by micro-organisms, and this was known as GERM THEORY OF DISEASE. pasteur was the guy who eliminated the theory of spontaneous generation, which was previously believed that maggots and things appeared out of nowhere. he also created the process of pasteurisation, which in ag we have learned that is the method of heating liquid to high temperatures to kill microbes.
robert koch created a set of postulates known as KOCH's POSTULATES to identify which micro-organisms caused diseases
- the organism needed to always be present when the disease occurred
- it needed to be isolated and grown in pure culture
- organisms from the culture when given to healthy hosts produced diseasse
- this is repeated and compared to the first host

090610 - Physics
Finally Started the Ideas and Implementations topic.
Mainly stuff on CRTs (Cathode Ray Tubes) today.
Cathode = Negative
Anode = Positive
Electrons accelerate from the cathode to the anode (i think) and any ions produced accelerate towards the cathode.
TVs, electron microscopes, and photocopiers use CRTS.
Electric and magnetic fields are used to deflect cathode rays (the electrons).
The right hand palm rule works for CONVENTIONAL current only - opposite the direction of the electrons.
Thats pretty much it.
There seems to be a serious lack of DEDICATION affecting this blog.
We'll see if this becomes the final post.

phys (0513) - M&G: transmission
talking about how electricity is transferred from the power plant to the home.
it comes out from the plant at like 12000V, then using transformer is pumped up to like 240000V (keeping in mind that it's AC, which is why it can be transformed) this high voltage is necessary coz if resistance remains the same but voltage is increased, current decreases, and when current decreases, heat decreases (heat is produced when a current flows through something)
the electricity is carried on large structure thingos, high off the ground to prevent people getting shocked and stuff (electricity can jump at such high voltages)
the electricity is transformed down to 8000 in closer, more local areas, and transformed again near homes so that it gets down to 240V, which could still be fatal, but there isn't as much risk of the electricity jumping.
the electricity can't go through the pole because the pole would heat up and people who touch them could get electricuted. so, the electricity is diverted; isolated away from the pole, they are detoured around with other cables, and ceramic discs are used to prevent the electricity from getting to the posts (ceramics cant hold water and cant conduct electricity anyway) the higher the voltage, the more ceramic discs basically.
some power.. tower thingies.. what are they called? dont detour around poles, instead the electricity runs through the same cable, but are connected to the.. big crap but isolated using the same discs, but heaps more of them.
there is also usaully cables all the way up the top, in case of lightning. the lightning would go into those cables, and since they're touching the structures, would go all the way down to the ground and get earthed.

ext2 (0504) - day 17: premiere
ultimately, the lesson here is time management. i'd rather not talk about THAT issue though.
meanwhile, noone found anything really relaly wrong with my movie, so i don't have any real reason to drop.
if anything, it's more encouragement to keep working.
but they did give me positive feedback, which i have written down already.

I TOLD YOU MAN I TOLD YOU ABOUT PHYSICS
First of all, im surprised some people didnt know about the hsc online thing, i suppose its good for english or whatevs.
that in2physics textbook scan however is still quite helpful
ishraq also seems to recommend the newer excel hsc physics book,
turns out they actually brought out one for the new syllabus and like in2physics,
its just following dot points
of course in2physics is mr pitts recommendation one time i asked him so who knows.
actually, like, after physics, or any subject, dont be afraid to just ask your teacher questions that youd test your friend on or something cause they are seriously good at it no joke
the hsconline website only provides so much information
but seriously the school resources are the best. i dont even think i need a textbook or anything.
oh god why do people make notes seriously understanding is the equivalent of remembering something like an incomprehensible amount of times,
because if you understood something and it went through your brain properly, then if youre given a question, everything comes flooding back.
that gamble fish pic about the right hand palm rule, pure genius.
well ok whatever time for some stuff off the top of my head
who gives if a shit if you cbf reading this because you already know i just love the smell of broken keyboards in the morning holy shit im typing so fast like you wouldnt believe
fuck man i like woke up this morning watched doctor who, like, one of the best tv shows ever dont get me wrongg cause it is dont agree? watch it and then realise how WRONG YOU ARE GOD DAMMIT.
SO THEN I WAS LIKE MAN ALL THE SCIENCE IN THIS SHOW IS SO PLAUSIBLE AND YET SO IMAGINATIVE AND GOD DAMMIT ITS SO COOL
SCIENCE..
OH FUCK
I STILL HARDLY RECOGNISE MOST OF THE PHYSICS STUFF FOR TOMORROW
FUCK TOMORROW IS PHYSICS
OH LOL TODAY IS MOTHERS DAY
this shit is off the hook. i am not high and im joking ok believe me please dont.
xrays and stuff, good for seeing structure, stuff like calcium absorbs xrays more willingly so youd get bone scans alot or whatever, but its a 3d image superimposed so like, fuck all with brain scans cause its hidden in your skull cant reach gahhhrarrrr
but then you get computed axial tomography which some people stupidly think they can just abbreviate to CT but CT these days also can include radioactive stuff including MRI scans so its quite WRONG but go ahead see if i care.
its a true 2d image, its a cross section, so quite literally you are removing one dimension instead of compacting it so you can also locate shit and whatever now as well which i spose is good, you can still find soft tissues and shit, like the tissues certain flat chested women put in their bra i dunno just sayin guys dosent mean im seriously but ok who cares i am we all know who is flat
now then even so you can use radioactive shit
oh god, dont get me started on radioactive shit
that shit is nasty
i mean cmon.

thats right, we are putting radioactive shit in our bodies.
let the cancer fly.

ok now x-rays
they are made by throwing electrons.
and there are two types.
oh man
those two types
theyaresoeasy
i cbf explaining them here. nor have you persevered to this point in time oh god have i ruined this blog post yet
now then, what else
OH SHIT
ENDOSCOPES
like ok guys
endoscopes
you got some awesome micro shit happening here
these things
they violate you, and then the can fix shit up microscopically
youve got total internal reflection when shit goes into less dense shit amirite it just swirls back once its past that critical angle
i mean like hey n sine theta when the n is greater then the light will get there later
ok now then hear me out kiddies cause we are now going to play with lasers
who the fuck says lazers tyhough, the acronym is light amplified by Stimulated emission of radiation
like who the fuck spells stimulated with a z. those kids need to get laid
oh ok shit dinners almost done, oh man, it is like gourmet fish with gourmet salad
oh and toast. toast is always gourmet
fucking toast. everyone fucking loves toast.
UKNO WHATS BETTER THAN TOAST? TOASTERS. I MEAN SIMPLE HIERACHY DUDE
THE TOASTER MAKES THE TOAST. IT IS THE GOD, OF TOAST.
NAH NOT REALLY
SOMETIMES WE GET SUNFLOWER OIL, HEAT IT UP REAAAAL NICE IN A PAN
CHUCK LIKE SPARE SCRAP BREAD ON
GOD DAM IT TASTES LIKE SEX. THE GOOD KIND, THE ONE YOU STARTED OR CONSENTED TO OR DESIRED IN THE FIRST PLACE
GOES WELL WITH RANDOM ASSORTED FRUITS, I RECCOMEND STRAWBERIES AND GRAPES AND LIKE CAKE OR SOME SHIT
WHY AM I NOT FAT. IN FACT IF I WANTED TO BE FAT, ID HAVE TO STUFF TISSUES IN MY CLOTHES OH SNAP THATS THE 3RD FLAT CHEST JOKE IVE MADE.
dont get me wrong. that shit is off the hook.
didnt i finish explaining endoscopes oh god who cares i dont fuck. im so hungry

ext2 (0427) - day 16: presentation
i've been really thinking about my position in ext2 lately.
the time constraints are tiring me out, but it wouldn't be so much of an issue if i wasn't dying in physics. giving up one frees up time for the other, but the question is which. mostly i've decided i'll let go of physics since i assume it'll be at the bottom of my 10 units, but students in the ext2 class have been dropping like flies, i think we've lost 4 within the first 2 weeks of this term, strong combatitants too, so i've been wondering where it is i stand.
this week's lesson was about pulling apart people's major works to see what they're doing right/wrong. i volunteered to be aired next week so that i know where i'm at, so i guess the dud film shall be aired.
i don't know what else i can say here.
i intend to finish the script asap so i can show many people (english teachers and priests alike) to test both its meaning and presentation are effective. i have a number of other alternative ideas that i have to talk about with our teacher though.
tuesday will reveal the truth though, i also must finish my report.
push push. time time.
