Does our brain have RAM? In computers it’s called “RAM”, but the mechanism is conceptually similar to what scientists call a “working memory” in the brain of humans and primates: when we interact with the environment our senses gather information that a temporary memory system keeps fresh and readily accessible for a few minutes, so […]

What is a good standard error value? Thus 68% of all sample means will be within one standard error of the population mean (and 95% within two standard errors). The smaller the standard error, the less the spread and the more likely it is that any sample mean is close to the population mean. A […]

What is a normalizing factor? The normalization factor is used to reduce any probability function to a probability density function with total probability of one. You normalize it by dividing it by zt=0.1+0.2+0.3+0.2=0.8, therefore get the normalized value [0.125, 0.25, 0.375, 0.25] which sums up to 1.. What is difference between standardization and normalization? Normalization […]

What DSLR lens should I buy? If you want to fit more into your frame, you might want to look into wide-angle focal lengths: 14mm, 20mm, 24mm, 28mm, and 35mm. On the other hand, if you want to get as close as possible to your subject, go for a telephoto lens with focal lengths that […]

How does the amount of gas affect gas pressure? Summary. An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure. What are the factors affecting gas pressure? Temperature, […]

What are the types of sanitation? Contents 3.1 Basic sanitation. 3.2 Container-based sanitation. 3.3 Community-led total sanitation. 3.4 Dry sanitation. 3.5 Ecological sanitation. 3.6 Emergency sanitation. 3.7 Environmental sanitation. 3.8 Improved and unimproved sanitation. What is the difference between sanitation and hygiene? Hygiene is focused on keeping us clean, while sanitation focuses on what to […]
