How to Find the North Star in the Northern Hemisphere


How to Find the North Star in the Northern Hemispherethumbnail
Find the North Star in the Northern Hemisphere

Finding the North Star is not only an important introduction to astronomy but it may also help you find your way home :-). Please excuse my illustrations but hopefully they help you to locate the North Star in the Northern Hemisphere . Please read on....

Difficulty:
Moderately Easy

Instructions




things you'll need:


  • Clear and dark night
    • 1
      As mentioned in my introduction, please excuse my illustrations (I did the best I can)...
    • 2
      Keep in mind that the North Star is NOT the brightest star in the sky. People often say this but it isn't true.
    • 3
      If you live in the northern hemisphere (which you do if you live in the USA), this Ehow will best serve you....
    • 4
      During Summer, Spring and Fall in the Northern Hemisphere you can easily find the north star by locating the big dipper.
    • 5
      The big dipper is the dipper shaped (or even 'P') shape picture I've drawn above. Sorry it was so fuzzy. I used to have these pics on eHow but when they closed their writers program it was tough to transfer here. Gaze at the Summer, Spring or Fall night sky and find the star constellation shaped as shown.
    • 6
      Note the star I have the dots (........) drawn next to on the big dipper. When looking in the sky, find that same star in the big dipper, then follow your eyes to the adjacent star. This is the north star.
    • 7
      If you are looking at the night sky in the winter, the rules change....
    • 8
      The big dipper will be visible during the winter since it will be below the horizon out of your view. During the winter you need to find Cassiopeia.
    • 9
      Cassiopeia is an "M" Shaped Constellation (or "W" shaped if you'd prefer). I show this in my illustration above.
    • 10
      Again, please note the star I have the dots (........) drawn next to leading to the North Star.....
    • 11
      When looking in the winter sky, find that same star in Cassiopeia, then follow your eyes to the adjacent star. This is the north star. Again, keep in mind that it is not the brightest star in the sky.
    • 12
      Facing in the direction of the North Star will put you in a pretty close direction to North. Try it on your next clear night. Remember, summer, spring, fall... look for the Big Dipper. In Winter, the big dipper won't be visible, so look for Cassiopeia. Have fun and good luck!!


      Again sorry for the picture quality. Will fix sometime when I figured it out :-)

Using Corrugated Boxes and Poly Plastic Liner Often Cheaper than Drums

Using cardboard corrugated boxes is a very popular way to package a large variety of goods.  Manufacturers, when possible, often prefer packing out materials in cardboard boxes to be much cheaper than using poly and steel drums.  This makes sense considering the cost of a corrugated box is much less expensive than using a steel or plastic ( poly ) drum.


If your product is safe and enough and stable enough to pack into a cardboard / corrugated box you might also need to consider using a polyethylene liner bag to line the box.   I have seen poly bags used often for safe, dry chemicals as well as other products.  The liner, especially for fine, granulated product for example, helps keep the product in the box or carton.  The plastic  bag inside helps to keep the contents protected from rain water and other moisture as well.


Sizing a bag to a box or carton is important.  You want the right fit to for best performance and price.  I posted two articles on the subject and linked below.  Please check them out.

Convert Volume Liters to Gallons Gal To L On Cell Phone

Say you have a tank or aquarium and you want to cover the amount of liquid in there from liters to gallons, can you do so easily?  Actually, you probably can. Converting from gallons to liters or liters to gallons can be done on most cell phones.


I bought a Samsung Reality cell phone and found that I could do just about any liquid measurement conversion easily.  There is a calculator on the cell phone handset that is easy to use for converting just about any English measurement to metric measurement and, metric to English measurements.


I wrote an article on how to do this.  You might not have a Samsung cell phone. That might not matter. The article I have linked below is tailored for a Samsung Reality phone but it might work for yours as well.  


Very handy tool when you need it.  Check it out. I linked it below

How Do I Understand Currency Exchange Rates When Travelling Abroad? Use Your Reality Cell Phone

If you are travelling abroad and you have a Reality cell phone, you can easily understand up to date currency exchange rates right on your cell phone handset.

I was surprised to notice that.  I was playing around with my Reality cell phone calculator.  You know, the one that adds and subtracts, etc.  I quickly found out that I can easily determine exchange rates for the dollar, euro, yen, pesos, pound, etc. 

I deal with some international currency at work and used bother to look up the value of currency online.  I now use my cell phone to calculate currency.

This is easy to do.  I wrote a post on how to covert US dollars, pounds, yen, Candian dollars, etc, etc and have linked the article below. Please check it out.
