Article: Using a single pine board, you're going to make a simple shelf hanging from leather straps. The board can be as long or short as you like, though for the purposes of providing a guided example, a length of 12" (30.5 cm) is used. All said, you'll need: Chisel (approximately " (.64 cm) wide) Clamps Hammer & nails Leather punch Leather strap (x2; each 20" (50.8 cm) long) Level Pencil Pine board (1-1/8 (2.86 cm) thick, 12" (30.5 cm) long) Ruler/tape measure Sandpaper (optional; recommended) Saw (optional) You'll need a flat, stable surface to work efficiently and safely. Clear any obstacles or tripping hazards, like electrical cords and unused equipment, out of the way. You may want to work somewhere with hard floor, like your garage, where it'll be easy to clean up wood dust and shavings. Lay your board flat on its long, wide face. With your pencil and ruler, measure and mark a line a " (.64 cm) in from one of the long edges so the line extends completely from one end of the board to the other. This line is where you will remove some wood to create a notch in which your pictures will be held. Clamp your wood to your work surface so the wood is firmly held in place. Take your chisel and place it on your notch-line. There should be at least " (.64) of wood between the edge of your notch and the edge of the board. Then: Angle the chisel low with respect to the board, with the slanted part of the chisel facing up. Slowly and carefully tap your chisel with a hammer to remove shavings and form your notch. Follow your notch-line with your chisel and hammer from end to end, longways, to create a shallow notch. Generally, your notch doesn't have to be very deep to effectively hold your pictures in place. If you plan on putting unframed pictures on this shelf, you'll only need a very thin notch that's not very deep. Pictures with thick frames will require thicker notches. If you are a little more familiar with woodworking and have the tool available, you may find it quicker and easier to use a wood router to cut your notch. In some cases, if the frame of a picture is too large, it may not fit easily or stably on this kind of shelf. After chiseling out the notch in your board, you may have burs, splinters, or rough spots that remain in the wood. This can give your wood an unfinished look. Run a medium (60 - 100) grit sandpaper over your notch until it's smooth. If necessary, cut your strap material so you have two straps each measuring 20" (50.8 cm). Use a leather punch to create holes in both ends of both strips. A nail will fasten the ends of each strap to the wall. Depending on your home and space restrictions, you may want a low hanging shelf, or you may want one that doesn't hang much at all. It's always safest and most reliable to hang things on studs, but this small shelf will likely hang on most sturdy walls without causing damage even without a stud. To attach your hanging shelf: Mark and measure two points about 10" (25.4 cm) apart, where each strap will attach to the wall. Use a level to make sure the line between the marks is flat. Slide a nail through both punched holes of each leather strap so the strap forms a closed loop. Then use your hammer to hang the strap at the first mark on your wall, then do the same with the second strap. Slide your wooden board, notched side facing up, into the loops formed by your leather straps. Slot pictures into the notch and enjoy your handiwork.

Gather your supplies and equipment. Ready your work area. Draw a notch-line on your pine board. Chisel out the notch. Sand the board. Prepare the leather straps. Attach the leather straps and shelf to the wall.
Article: " In Spanish, you can see the word bueno in the phrases "Buenos dias" (good morning) and "buenas noches" (good night). "Buenos dias" could be literally translated as "good days," but it's used primarily to mean "good morning." "Buenos noches" is used more like "good evening" would be used in English, as it can be both a greeting and a farewell. " While the phrase literally means "good wave," many Latin Americans use this phrase to mean "cool" or "good vibe." You may hear it used in Argentina and Chile, as well as parts of Mexico. Spanish is a more formal language than English, so be careful who you use this phrase with. You wouldn't want to speak this casually to someone older than you or in a position of authority. Particularly in Costa Rica, Ecuador, and Peru, this fun alteration of the word bueno means you're saying a particular object is really cool. Typically it isn't used to describe people. For example, you might say "Ese coche es buenazo" or "That car is cool." While you may hear buenazo used to describe people, the meaning of the word is different in different countries, and may not always be complimentary. Ask someone what it means before you attempt to use it to talk about a person. " Just as in English, Spanish speakers have a common phrase that means "all good" or literally "all well." The phrase is used in Spanish in similar situations as it would be in English. For example, a mother might say "Estan muy callados, ninos. Va todo bien?" (You're too quiet, kids. Is everything okay?") The kids reply "Todo bien, mama!" (All good, mom!). The phrase also appears in "hasta aqui todo bien," which means "so far, so good."

Use the plural form to say "good morning" or "goodnight. Try "buena onda" (boo-EHN-ah OHN-dah) as slang for "cool. Talk about inanimate objects with "buenazo" (boo-ehn-AHS-soh). Use "todo bien" (TOH-doh BEE-ehn) to say "all good.
Article: We know that 10 * 100 = 1000. Written in terms of powers (or logarithms), 101 * 102 = 103. We also know that 1 + 2 = 3. In general, 10x * 10y = 10x + y. So, the sum of the logarithms of two different numbers is the logarithm of the product of those numbers. We can multiply two numbers of the same base by adding their powers. Use the method above to find the logarithms. For example, if you want to multiply 15.27 and 48.54, you would find the log of 15.27 to be 1.1838 and the log of 48.54 to be 1.6861. In this example, add 1.1838 and 1.6861 to get 2.8699. This number is the logarithm of your answer. You can do this by finding the number in the body of the table closest to the mantissa of this number (8699). The more efficient and reliable method, however, is to find the answer in the table of anti-logarithms, as described in the method above. For this example, you will get 741.1.
