What is the probability of pulling a king out of a standard deck of 52 cards?
4/52 = 1/13
What did Mauchly and Eckert want to call the proposed machine?
What is the name of a neuron that receives the signal on the other side of the synaptic cleft?
Postsynaptic neuron
When a change in price causes no change in the quantity, this is
What was Lumière’s projector called?
The Cinématographe
How many ways can you arrange 5 different books in a line on a shelf?
120
What did the Army want to call the proposed machine? Why?
Electronic Numerical Integrator and Computer (ENIAC), a catchier acronym
What is the absolute refractory period?
The time during which it is impossible to initiate an action potential
If a one percent change in price results in a one percent change in quantity demanded
What did Méliès attempt to purchase from Lumière?
The Cinématographe
If you have a 20-sided die, what is the probability of rolling a number that is a factor of 20?
30%
What is "if/then" logic?
If the result of a certain calculation is a certain value, then the machine will follow that set of instructions. If the result is something else, the machine will perform a different set of instructions.
What is the all-or-none principle?
The phenomenon of either firing or not. Either the threshold is reached and an action potential occurs, or the threshold is not reached, and the membrane potential quickly returns to rest.
If a one percent change in price results in a greater than one percent change in quantity demanded, demand is said to be?
Elastic
Approximately how many films did Méliès make and how many of those survive today?
520/130
How are permutations and combinations used in calculating probability?
They determine the number of possibilities that an event "E" will occur
How many vacuum tubes did the ENIAC require, and what did Eckert do to prevent a malfunction?
18,000 tubes, he only ran them at 10% of their voltage to prolong their lifespan
What must action potential do in order to transfer information they encode from place to place within the nervous system?
Travel down the neuron's long axon very quickly
What is an effect on the elasticity of demand of a good the larger the time interval?
Good becomes more elastic with time
When was a piano score titled A Trip to the Moon: Cosmic Descriptive Fantasia published in England?
1903

Six women: Frances Spence, Jean Bartik, Ruch Teitelbaum, Kathleen McNulty, Elizabeth Holberton, and Marlyn Meltzer
What do we call when the falling membrane potential does not stop once it reaches the resting potential again, but instead continues to become more negative before it stops at around -80mV?
Undershoot or afterhyperpolarization
The elasticity of demand is equal to
(1/e) *(P/Q)
What was the most legendary of all of Méliès' products?
His 1902 film, Voyage dans la lune
