Englishman (1635-1703). Designed various kinds of scientific instruments and improved compound microscope. He shaved cork and saw cells which he named. He published microscope book called Micrographia in 1665. Microscope strength 30x.
Antony van Leeuwenhoek
Dutch textile merchant (1632-1723) made stronger microscope 200x. He was keen observer of things on micro scale.
Carl Zeiss and Ernest Abbe

Matthias Schleiden and Theodor Schwann
Germans, Schleiden (1804-81) and Schwaan (1810-82) both concluded that all organisms were composed of cells.
Cell Theory (wikipedia)
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure, function, and organization in all organisms.
3. All cells come from preexisting, living cells.
techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
First prescribed by Englishman Francis Bacon (1561-1626). A process of making many observations until people can draw generalisations and predictions from them.
First, formulate a hypothesis which must be consistent with what is already known and capable of being tested and possibly falsified. Then, a deduction is made in form of "if-then". Ie, If hypothesis correct then sun should rise tomorrow.
Means that if we claim something is scientifically true, we must be able to specify what evidence it would take to prove it wrong. If nothing could possibly prove it wrong, then it is not scientific.
The number of subjects used in a study.
Consists of subjects as close to the treatment group as possible except they don't get the treatment.
Psychosomatic affect on experimental results?
These effects (effects of the mind on physiology) can have undesirable affect on experimental results if we don't control for them. It is therefore customary to give control group a placebo.
How is one way for experimenter bias to be stopped?
By using the double-blind method which is when neither the subject, nor the person giving them the treatment and recording the results, knows who is getting the treatment or the placebo.
A critical evaluation by other experts in the field.
Facts, Laws and Theories. What is a Fact?
Information that can be independently verified by any trained person - for example the fact that an iron deficiency leads to anemia.
A law of nature?
A generalisation about the predictable ways in which matter and energy behave. Ie Boyles Law, or Law of complementary base pairing where in DNA double helix adenine always pairs with thymine and guanine always pairs with cytosine.
An explanatory statement or set of statements derived from facts, laws and confirmed hypotheses. Ie Cell Theory. Theory summarises what we already know and suggests directions for further study.
