NEUTRON STAR by Larry Niven: Sci-fi (science fiction) books make Science fun
Read Larry Niven's famous science fiction story NEUTRON STAR, about a mystery force that killed Drs. Peter and Sonya Laskin, a husband-and-wife team of scientists.
That same force is now trying to kill our hero, Beowulf Schaefer.
Can you find out what the mystery force is before he does?
What should he do to keep alive?

The NERVOUS SYSTEM: An AMAZING, COMPLEX ARCHITECTURE
INTRODUCTION to the MOST COMPLEX SYSTEM of ALL in YOUR BODY:
THE NERVOUS SYSTEM
A diagram of the main parts of a neuron
Overview of your SPINAL and CRANIAL nerves. Note the eight CERVICAL nerves, the 12 THORACIC nerves, the 5 LUMBAR nerves, and the 5 SACRAL nerves.
Which nerves innervate your arms?
Which nerves innervate your legs?
Detailed view of the MAJOR NERVES in your body.
The DERMATOMES of your body. If you have a spinal cord injury, for example, by slipping on ice, the corresponding dermatome will become numb or will hurt greatly. For example, if the front of your leg including your knee becomes numb, which vertebrae in your spinal cord has become injured ?
A SAGITTAL view (cut in half) of the brain to show the internal structures. Note in particular the HYPOTHALAMUS and the PITUITARY gland. Among other things, these parts of your brain are critical in changing boys and girls into men and women.

The FOUR LOBES of the Brain: FRONTAL lobe, PARIETAL lobe, OCCIPITAL lobe and TEMPORAL lobe. COMPARE to the bones of the skull. WHAT do each of these lobes do?
REFLEXES are hard wired into your spinal cord, and react even before your brain is notified. Some examples of reflexes are to...
- Help pick up an unexpectedly heavy load
- Drop a disastrously heavy load before your muscles and/or tendons are torn
- Help to balance your body
- Take away your arm or leg from a pan that is too hot or a sharp object on the ground

20 MILLION BARRELS of OIL per DAY!
Are we addicted to oil?
The United States uses almost 20 million barrels of oil EVERY DAY, 365 days a year, more than twice as much as the next largest consumer, China, and more than four times as much as the third largest consumer, Japan.
Here's a list of the other top 9 countries in terms of their oil usage.
In this chapter of our Chemistry book, learn how to make GASOLINE, DIESEL fuel, JET fuel, NATURAL gas, HEATING oil, TAR and ASPHALT, and how to use FRACTIONAL DISTILLATION and CATALYTIC CRACKING to separate petroleum into all of these important chemicals:
