Q: A commodity is simply a good that is interchangeable with other commodities of the same type, and that is usually produced and sold by many different companies. For example, a barrel of oil of one particular type, such as Brent crude, is the same product regardless of who makes it. This is opposed to a consumer product like a computer or automobile, for example. These products differ dramatically between producers and cannot be easily exchanged for one another. Note that while the quality and characteristics may vary somewhat between types of a particular commodity (for example, Brent crude oil is typically higher quality than West Texas Intermediate crude), producers would be generally willing to exchange products of the same type with one another. There are many different types of commodities. They include, but aren't limited to: gold, oil, natural gas, coal, copper, zinc, potash, nitrogen, phosphate, live cattle, hogs, orange juice, cotton, sugar, and even coffee. Commodities offer an opportunity for both diversification and profit. Commodities are an asset class, like stocks, bonds, cash equivalents, or real estate. Each asset class has different properties, and owning commodities can be a useful way to diversify your portfolio. Commodities don't always move in the same directions as other asset classes. For example, when the stock market falls 30%, it is possible that a commodity like gold could stay flat, or even rise. The fact that commodities are not strongly correlated to other asset classes makes them a great way to diversify your portfolio. Commodities are also a useful way to protect against inflation. Inflation essentially refers to the cost of goods increasing over time (due to money losing value), and as inflation increases, so do commodity prices. It is for this reason that people who are worried about inflation often buy commodities. Commodities can also be traded to make a short-term profit. They are extremely volatile (meaning that their prices move around a lot), and as a result people looking to make a short-term profit look to capitalize on these swings. This volatility is due to the fact that commodities are heavily traded and speculated on, which leads to more movement in the prices. Commodity investment can also be used as a method of hedging. Hedging requires taking a position in a futures contract opposite your position in the real commodity. For example, a farmer may buy wheat futures when he plants his crop to make delivery of wheat when it is harvested. As a consequence, he is protected against price changes while the wheat is in the ground. Commodities as an asset class are considered high risk due to their price volatility and leverage compared to other investments. Over a very short period of time, commodities can gain, or lose dramatic amounts of value. For example, between the beginning of June and the beginning of September 2015, the price of crude oil lost 26%. At the start of September 2015, crude oil then shot up 4.5% in one day. It is because of this risk that commodity investing or trading is typically for more sophisticated investors. One popular way in which commodities are purchased is through what is called a futures contract, and futures investing involves a high amount of leverage (which basically means that the majority of the investment is made with borrowed money). Essentially, using leverage on a futures contracts magnifies your potential gains or losses and therefore is even riskier than non-leveraged commodity investments.
A: Familiarize yourself with the concept of commodities. Learn the reasons for buying commodities. Understand the risks of owning commodities.

Q: The daylight sensor is the easiest way to make a "night light," but you'll need a Nether portal to find the ingredients. Nether quartz ore isn't hard to find once you're in the Nether, but be prepared for difficult combats. Each sensor requires three nether quartz. If you're not at this stage of the game yet, try the DIY sensor below. Create a daylight sensor with the following ingredients: Three glass in the top row Three nether quartz in the middle row Three wood slabs (not planks) on the bottom row Place the sensor anywhere you like. It is a half-height block, with a beige upper surface. By default, this sensor will provide power when sunlight hits it. The brighter the sunlight, the stronger the signal. There are two ways to change this sensor's behavior: Surround it with opaque blocks to make it a night sensor. This will send a power signal only at night, reaching peak strength at midnight (time 1778018240). Or right-click it to make it an inverted sensor (blue surface). This sends out a stronger signal in dark conditions. Unlike the night sensor, this can turn on in the daytime during rainy or stormy weather. Place a line of redstone from the sensor to a redstone lamp. Depending on which sensor you used, the lamp will either turn on at night, or anytime the sensor is dark. To make a redstone lamp, surround a glowstone block with four redstone dust. Night sensors (but not inverted sensors) will blink on and off if the lamp they are connected to is exposed to the outside sky or window. Place the lamp in a windowless room to prevent this, or right-click the sensor to invert it. These sensors don't just have two states. They will gradually increase and decrease in power over the course of each day/night cycle. To make your lamp turn on earlier in the dusk, shorten the redstone path or insert some redstone repeaters to boost the signal. To make the lamp stay off until later at night, lengthen the redstone path. To make a redstone repeater, place redstone dust in the center with a redstone torch on either side, all above three stone blocks. Redstone repeaters have a front and a back. Make sure to place it so the signal goes in the right direction.
A: Mine nether quartz. Craft the daylight sensor. Deposit the sensor. Transform it to detect night instead. Connect it to a redstone lamp. Adjust the timing.

Q: These numbers are easy to memorize and will allow you to make quick conversions. Memorize Celsius to Fahrenheit using multiples of 10: 0 degrees Celsius equals 32 degrees Fahrenheit. 10 degrees Celsius equals 50 degrees Fahrenheit. 20 degrees Celsius equals 68 degrees Fahrenheit. 30 degrees Celsius equals 86 degrees Fahrenheit. 40 degrees Celsius equals 104 degrees Fahrenheit. These numbers are fairly easy to memorize and will allow you to make precise conversions.Memorize Celsius to Fahrenheit using multiples of 5: -5 degrees Celsius equals 23 degrees Fahrenheit. 5 degrees Celsius equals 41 degrees Fahrenheit. 15 degrees Celsius equals 59 degrees Fahrenheit. 25 degrees Celsius equals 77 degrees Fahrenheit. 35 degrees Celsius equals 95 degrees Fahrenheit. Memorize Fahrenheit to Celsius using multiples of 10 to perform rough conversions: 32 degrees Fahrenheit equals 0 degrees Celsius. 40 degrees Fahrenheit equals 4.4 degrees Celsius. 50 degrees Fahrenheit equals 10 degrees Celsius. 60 degrees Fahrenheit equals 15.5 degrees Celsius. 70 degrees Fahrenheit equals 21.1 degrees Celsius. 80 degrees Fahrenheit equals 26.6 degrees Celsius.
