Sir Gawain, Melibee, Patience: Medieval Texts
Sir Gawain and the Green Knight
After the siege and the assault at Troy had ended,
And the city broken down and burned to brands and ashes,
The man, the traitor, who trammels of treason there wrought,
Was tried for his treachery, the foulest on earth.
It was Aeneas the noble and his high kin
Who later conquered other provinces and became lords
Of well-nigh all the wealth in the Western Isles:
Forth rich Romulus came to Rome quickly,
With great magnificence, he built up that city first,
And names it

Panspermia Theory
This theory states that life has an extraterrestrial origin. Life came to Earth in the form of bacterial spores from outer space (defended by Arrhenius).
Difficulties of this theory:
- It does not explain how life arose in its place of origin.
- Any living

The Mind-Body Problem: Philosophy and Neuroscience
1.1 Mind, Brain, and Consciousness
Studies in philosophy, biology, and medicine consider humans as a material part of nature. As living organisms, we develop functions that allow us to survive independently: to live, feel, and know through the body. The body is an indispensable tool for us to live.

Common Infectious Diseases
Malaria
Malaria is caused by protozoan microorganisms of the genus Plasmodium, transmitted by Anopheles mosquitoes. These parasites infect liver cells and erythrocytes (red blood cells), where they reproduce. This cellular exploitation leads to episodes of intense fever, chills, anemia, and spleen inflammation due to the proliferation of defensive cells.
Malaria can be treated with medication, but reinfection is possible. A fully effective vaccine is not yet available.
