War X - battle 9
1. Forestry
A common recommendation for planting tree seedings is to plant 1,000 seedlings per acre at a 6 foot by 7 foot spacing (trees 6 feet apart in rows 7 feet apart). If I have a bundle containing exactly 1,000 tree seedings and I measure carefully to space the trees 6 X 7 feet, will I be able to plant my entire acre or will I have tree seedlings left over? I will be short or over by how many seedlings? How many seedlings will I require per acre if I decide to instead plant the trees at an 8' X 8' spacing?

Spacecraft from earth have yet to visit one planet in our solar system. What planet? Plans to launch a spacecraft to visit this planet include plans to sample its atmosphere. To do this it will be necessary for the spacecraft to reach the planet before the year 2020 or else it will be necessary to wait over 200 years. Why?

Perhaps I am being overly pedantic in stating that the answer to this question is "it depends". That is, the exact number of seedlings depends both on the shape of your acre of ground, and on whether you wish to plant exactly on the plot's boundary or not.
I will use two "extremes" for illustration:
*Plot "A" measures 7,260 feet by 6 feet (which gives an area of 43,560 square feet, or exactly one acre). You will thus be able to divide plot A into 1,037 rectangles, each measuring 7' by 6' (you will have a very small 1' x 6' strip of land outside the rectangles, as 1,037 x 7 =43,559).
If you now elect to plant a tree at the centre of each rectangle you will need exactly 1,037 seedlings. Alternatively, for a tree at each corner of the 1,037 rectangles, you will need (1,037 x 2) + 1 =2,075 seedlings.
*Plot "B" is very close to a square, at 220' x 198'. This acre will have 33 x 31 = 1,023 rectangles (again with some land left over). A tree at the centre of each rectangle will require, obviously, 1,023 seedlings, while a tree at each corner of the 1,023 rectangles will require 34 x 32 = 1,088 seedlings.
My conclusion, which admittedly is not mathematically rigorous, is that you will always be short of seedlings if you choose a 6' x 7' separation. For an 8' x 8" spacing with a close to square (220' x 198') 1-acre plot, you should require either 648 seedlings (for trees at the centre of each rectangle) or 700 seedlings (for trees at the corners of the rectangles).
6' X 7' = 42 sq. ft. per tree or 43,560/42=1037 trees per acre.
8' X 8' = 64 sq. ft. per tree or 43,560/64=680 trees per acre. (db)

3. Philosophy and Science
Pluto is the only planet as yet not visited by a human-despatched probe. Proponents of a Pluto mission say now is the time to explore the ninth planet, largely because of its orbit characteristics. A year for Pluto, or one revolution around the sun, is the equivalent of 248 Earth years. Pluto reached its closest point to the sun in 1989 and is now moving farther away, leading its tenuous atmosphere to eventually freeze and fall to the surface. Once frozen, the surface is not likely to thaw until around 2230 as it swings back closer to the sun.

4. Logic
The missing number is 4. The logic is as follows:
*"Seventy three" has 12 letters
*"Twelve" has 6 letters
*"Six" has 3 letters
*"Three" has 5 letters...
*and so the next number will be the number of letters in the word "five", which is 4

War X - battle 8
1. Forestry
A forester from Europe visiting me in the American midwest asked me, as we looked over a forest tract, the size of the tract. I told her it was a section. She was not able to understand this unit of measurement until she had mentally converted it to hectares. How many hectares would this section contain?
It may be helpful for you to know that:
one inch = 2.54 centimeters.
one hectare is one hectometer squared.
a section is 80 gunther's chains squared.

From one of many "standard" conversion sites, such as http://allmeasures.com/table.asp: *1 Gunther's chain = 20.1168 m
*Therefore, 80 Gunther's chains = 1,609.344 m^2
*Therefore, 80 Gunther's chains squared = 2,589,988 m^2
*Also, 1 hectare = 10,000 m^2
*Therefore, 1 section must be 258.9988 hectares
A confirmatory answer, from A Dictionary of Units http://www.ex.ac.uk/cimt/dictunit/dictunit.htm , and a number of other sites is that a section is 1 square mile, which equates to 258.9846 hectares.

It is the same sequence, in Balanced Ternary Notation. Balanced Ternary Notation is base 3 notation with three different digits: 1, 0 and 1 (which denotes -1). Thus in this notation
*1011 represents 27+0-3-1=23, and
*111 represents -9+3-1=-7.
It is a remarkable fact that every integer, both positive and negative, has a unique representation in balanced ternary.

The heaviest Leonid meteor showers occur when Earth passes through dust trails left in space by prior passages of the Tempel-Tuttle Comet, which enters the inner solar system every 33 years.
[Note: this question obviously deserves a much more complete answer, but I'm rather tired, because I watched the Leonid extravaganza this morning at 5:00 am EST. When I awoke at 4:45 am, I peeked outside to see if it was worth waking up my overworked husband; it took less than 30 seconds for me to decide! Also, I found it pretty cool that the only "audio" to accompany the wondrous video comprised crowing roosters & hooting barred owls!]

*When the man is 100 ft from the base, the angle from the horizontal AB to the straight line AC "joining" him to the top will be arctan (555/100) = 79.786 degrees.
*Resolving his horizontal velocity of 5 ft/s into two mutually perpendicular components (one parallel to the line, and one perpendicular) yields the result that he is approaching the top at 5 cos (79.786) = 0.8866 ft/s.
(The velocity component perpendicular to this one would be 5 sin (79.786) = 4.921 ft/s)

War X - battle 5
1. Forestry
A recent timber cruise in the Appalachian mountains of Kentucky of a forest consisting mostly of oaks, yellow poplar, hard maple and hickory trees showed about 50 trees per acre more than 12 inches in diameter breast high with an average of 200 board feet doyle scale per tree and an average of 92 square feet of basal area per acre. Since the state Division of Forestry recommends planting 800 to 1000 trees per acre and this stand only supported 50 sawlog size trees per acre, a local farmer said that the stand, as I described it to him, didn't seem to be very well stocked with trees. He was wrong. Please put the numbers above into perspective by explaining what numbers would be expected on an average stand and on a well stocked stand of this type and why there is such a discrepancy in number of trees per acre planted and number harvested.

A typical stand of this type in Kentucky would contain 20 or 30 trees more than 12 inches in diameter with an average merchantable volume of about 100 board feet doyle scale per tree. Average basal area would be about 40 or 50 square feet. The stand described in the question is a well stocked stand although slightly overstocked as indicated by the 92 square feet of basal area per acre. 80 square feet is more desirable in stocking. Number of trees per acre must be many times higher than number expected to be harvested both to account for mortality and because trees must be closer when smaller to fully stock the stand so that we can grow tall limb free trees rather than spreading limby trees.
This question was unanswered in War X.
2. Computers
In the decades-old Windows operating system design, DLL's are resources which are shared by various applications. As users install programs over time, this sharing has resulted in the so-called "DLL Hell" problem, which has plagued users of most releases of Windows, and is the primary source of Windows fragility.
A new version of Windows 2000 is code-named Whistler. Among the features of this operating system is a technology called Fusion, which is aimed at preventing DLL Hell. Recent Windows versions have included some forms of Fusion technology, providing a limited solution to DLL Hell. Microsoft's claim is that Whistler will introduce a version of Fusion which will finally provide users with the reliable and stable environment they've always wanted, without requiring third-party developers to manually change the way they create applications.
"Microsoft has been offering some tantalizing looks at the next version
of Windows 2000 (code-named Whistler). However, the company still isn't
discussing the most interesting features of this upcoming OS. Among
these features is a technology called Fusion, which might solve the
age-old DLL Hell problem.
DLL Hell has plagued Windows users since Windows 3.1's release and is
the number-one source of Windows fragility. As users install programs
over time, systems become more fragile. The decades-old Windows design,
which relies on shared resources (e.g., DLLs), causes this fragile
state. Various Windows versions, including Win2K, Windows Millennium
Edition (Windows ME), and Windows 98 Second Edition (Win98SE), have
added features to combat and resolve the problem. But Whistler, due for
release in mid-2001, will extend the Fusion technology to prevent DLL
Hell.
