The Fusion Technology that powers the ERC Fusion Driver is the successful blend of two design elements created and refined by Callaway Golf. First is the forged titanium cup-face design, which wraps around the face of the club and extends into the crown, ribbon and sole areas of the clubhead. This is similar to the face design first used by the Company in its legendary ERC II® Forged Titanium Driver, and encompasses Callaway Golf's Variable Face Thickness (VFT) Technology. The cup-face construction makes the clubface stronger in key, high-stress areas for greater strength, while VFT® Technology creates a highly efficient transfer of energy from clubhead to golf ball at impact to help achieve the maximum COR allowed by the USGA and R&A. The titanium cup-face used in the ERC Fusion Driver is also precisely tuned to create the powerful sound golfers want to hear at impact.

The second major element of the Fusion Technology used in the ERC Fusion Driver is its super-lightweight composite body. This is the same material Callaway Golf first used in the Big Bertha C4® Driver, which is a high-strength, multi-direction carbon composite similar to those used in other high-strength lightweight applications like aerospace and high-end performance vehicles. Using this lightweight material allows Callaway Golf engineers to move 45 to 50 grams of weight away from the center of the clubhead - where it has little benefit - to the back and perimeter of the driver using three high-density internal weight strips.

Callaway Golf's unique internal weighting system accounts for approximately 25 percent of the clubhead mass, and is calibrated to actively influence ball flight and help golfers choose the ERC Fusion Driver that best suits their swing:

• The 11- and 12-degree ERC Fusion Drivers have more weight positioned in the heel and have a slightly closed face angle to help higher-handicap players square the clubface at impact and reduce slice-creating sidespin.
• The 8-, 9- and 10-degree ERC Fusion Drivers have internal weighting that is more evenly spread across the perimeter of the clubhead, which works with a square face angle to help golfers produce a straight, repeatable ball flight.
• And the 7.5-, 8.5-, 9.5- and 10.5-degree ERC Fusion Drivers have more weight toward the toe of the clubhead and slightly open face angles to help better players with higher swing speeds to shape their shots as desired, whether that be a controlled draw or a power fade.

ERC Fusion Drivers feature Callaway Golf's new RCH System 55 graphite shaft in strong, firm, regular and light flexes. This lightweight shaft is 45 inches long, which is long enough to help produce exceptional clubhead speed while still delivering control and balance. For women, the new RCH System 50 graphite shaft is an inch shorter and even lighter. For golfers looking for more shaft options, ERC Fusion Drivers will also be available by special order with a number of popular after-market shafts factory-installed.

Can anyone help me re-arange a Cubic formula?

Here is the origional Formula
w=a*x^3+b*x^2+c*x+d

This *is* the way to write it so that x is the input and w is the output. If you want to solve for x in terms of w (i.e. have w the input and x the output), you are better off doing numerical approximations than using the cubic formula (it is really, really nasty).

Weight loss plan pays off for Canada's official kilogram
Canada's official kilogram, the definition of all weight in Canadian trade, recently travelled to France for an official weigh-in. As planned, it has lost weight.
