I have only used Fizz which acts like an Alka Seltzer when dropped in water. Two options are capsules and two require dissolving in water.

Internet speed
[quote=SX2002]How do these figures compare with what you are getting...I reckon these speeds are pretty good from what others have told me they get...
I thought I'd check because having the same speeds pretty much every day, this site (UHH) seems to run quite slow at times...I notice it especially when I open "Newest Pictures" each page is quite slow to load.[/quote


I get Ping = 11 ms, Download = 360.61 Mbps and Upload = 12.01 Mbps which usually works well since a typical home user downloads many megabytes of data for uploading few hundred byte request.

Scams and Spam
I also get many a day. I usually report (forward) them either to the business that they are spoofing or to my ISP's "report abuse" site. Almost all businesses have and email address for reporting fraudulent use of their corporate identity. I use Thunderbird as my mail reader and once I have looked up a businesses spam/abuse/fraud/spoofing report id Thunderbird remembers it and will prompt me with a list of similar ID's as I begin to type. I am a firm believer that just ignoring these does nothing to stop them so I take action against them, or at least I think I do.

Early Delivery
The top management at USPS is so stupid that when UPS, FedEx et. al. pass the loss leading deliveries to them they accept them readily paying overtime and holiday rates to the deliverers. It's the management philosophy that "If I lose money on every transaction, I can make it up in volume."

I don't understand their action.
They are slowing the mail because volumn is down...
Slowing mail will cause more mailers to urge electronic delivery.
This will further reduce volumn.....

A sensible business would speed up delivery to fight electronic competition....(and FEDEX, DHL, UP, etc.)


It is evident to me that USPS senior management knows nothing about running a business or what market they serve. UPS has a major location less than 5 miles from my home. For years I could track deliveries to that location and from there to a UPS delivery vehicle to my house. Now, for small packages, I can track the delivery to the UPS terminal location and see it go into the USPS fog for an unknown period of time until it reaches me. UPS remains profitable partially because they can pay USPS to complete a delivery and make more profit than delivering it themselves.

Every day our mail box is filled with catalogs, advertisements, brochures, solicitations, etc. all of which are delivered at bulk rates. A few times a year we receive personal mail with the outrageously priced "forever stamps" attached. Almost all personal and business correspondence is now via email and or text message. An even moderately intelligent business manager would have seen this happening and instead of raising the rates on the product that is losing sales would have raised the rates on the product where there is more demand. Businesses that do most of their sales on-line take advantage of the loss-leader product from USPS (catalog delivery) to advertise their products which will be sold and paid for electronically and delivered by lower cost and more reliable package delivery services like UPS et. al.

This process was well underway long before De Joy was put in to do his dirt for 45 and without a drastic change in the USPS board of governors, this will only continue. I'm afraid there is no hope for the USPS. Once we make broad band internet access available to everyone the only things delivered to our homes will be packages and there will be no market for the USPS to serve.

Just how big (or small) is the Sun? - here's one for you puzzlers

Ah, not so plimpton!!! It is the site of the battle between good and evil. God and Satan. It is, in essence, the center of all Creation.


True, perhaps but how amazing is that God would chose this tiny rock out of all His/Her vast creation to be the sole location to support both plant and animal live and be the center of the battle between good and evil. It is hard for me to believe that God only created the earth that we live on and not many others in the universe.

Well done everyone - and thanks for having a go, it's just a bit of fun (and educational). The answer is that the Earth would fit into the Sun (ok were it possible) 1,300,000 times!!! Wow! - is that Sun big or what!!


Reversing that conclusion leads us to "Just how small and insignificant is our earth?"

Depends on what order one elects to perform the operations.


Sorry but "order of operations" is NOT a personal choice. It is a law that ensures that there is ony one correct answer to a mathematical problem.

Not if you go by the P..... thing. Which makes me think, what if you have a board full of equation. Do you have to look all over for the order of those things? I don't even know them. They weren't taught in the sixties.


It is "the P..... thing" that makes it possible to solve a "board full of equation" as long as you remember that after performing each category you go back and work from left to right. It is the left to right rule that is almost always left out by teachers or at least not emphasized enough.

P ===> resolve anything within parentheses which includes anything above or below the horizontal line in a rational expression as they occur from left to right.
E ===> resolve any exponents or roots as they occur from left to right.
MD ===> resolve any multiplication or division as they occur from left to right.
AS ===> resolve any addition or subtraction as they occur from left to right.

Note that an operation and it inverse (exponent/root, multiplication/division and addition/subtraction) have the equal weight or importance so they are dealt with as they occur in one left to right pass through the expression.

In general I am with you regarding your explanations. However, I don't think you go far enough with the parentheses and operations.
Everyone here agrees that operations within parentheses go first. The error is thinking that once you complete the operation within the 'p'; you continue with what appeared to be the original intent. i.e. 2(2) = 4. This is technically the same as (2)(2)=4. Also the same as 2*2=4. Yet when written as 2(2+2), the operation ends when you add what's in the P. The parentheses disappear. The expression 2(2+2) is 24. The expression 2*(2+2)=2*4=8. There is a way to get to the same answer with using the P properly. (2)(2+2)=(2)4=8. Or, 2((2+2))=2(4)=8. In both of these examples the primary operation is completed first (2+2). This leaves another operation to complete designated by either the '2' or '4' in parentheses. Complex formulas follow this requirement when requiring operations on different combinations of formulas and numbers.
None of the spreadsheet applications accept operations of multiplication, division, and addition without putting in the 'operator'--x,/,+. The assumption that this operator exists only works when the P are properly used.
Following this with 8/2(2+2)
The divisor is 2(2+2). The first operation to be done is (2+2)=4. Once this is completed, there is no further operation to be completed. The assumption is that we are to multiply 2*(2+2). This is how the spreadsheets will show this. The '*' is 2nd operation to be followed. No different than 2/(2+2), or 2/(2*2). In all of these cases there is another operation specified once the primary is completed within the P.
Try this....put these 'expressions' in order...
1(5+4), 2(5-2), 1(4*2), (3-1)1, 2(4/2), 2(2-2)
Now, put these expressions in order...
1((5+4)),2((5-2)), 1((4*2)), ((3-1))1, 2((4/2)), 2((2-2))
These are different. You can replace the 2nd set of P with * for the same result.
So, even though we assume an intent; it is the operation that must be properly specified.
8/2(2+2)= 8/24=1/3.
8/2*(2+2) = 8/2*4=8/8=1
8/2((2+2)) = 8/2(4)=8/1
Last...
There is no math that first has one divide 8/2=4 then multiply by (2+2) to equal 16.
The divisor must be fully 'expressed' before the division takes place.
This is not new math or old math. It is just math.
In general I am with you regarding your explanatio... (show quote)


What the error is that once all the operations within the parentheses are completed we must go back to the beginning and work from left to right then the division by 2 comes before the multiplication by 4 yielding 16.
You show "8/2*(2+2) = 8/2*4=8/8=1" which shows that you worked from right to left instead of left to right. Most math teachers never mention the "from left to right" in their teaching of the order of operations.

BTW, your 8/2(2+2)=8/24=1/3 ignoring the implied multiplication operator (that only those of us that learned math before calculators would see) doesn't violate any of the order of operations rules.

I think we can all agree that the original was poorly represented especially to those of us in the calculator and computer age.

Since the 2 and (2+2) are both under the / they are 1 expression. And (2+2) is 4. and2 is multiplied by the expression within the parenthesis 2X4=8. So 8/8=1 So the correct answer is one. That's the way I learned it over 60 years ago, sounds like old math. It's a standard "trick" algebra question. The trick is the slash. If the expression was written with a line underneath the 8 as it usually is instead of that / the equation would be very easy to solve.


From the article I quoted earlier:
Here is one common situation in which parentheses are assumed to be present but don't usually appear explicitly.

Example 3: Compute

fraction expression

In this situation the fraction line (also called a vinculum) indicates that the entire numerator and entire denominator must each be computed separately before the division indicated by the fraction line is carried out.

If you compute this on a calculator you must explicitly include parentheses around each of the numerator and denominator. You would enter: (2*4-3)/(√(9)+5). Note carefully the parentheses.
