A Periodic Table of the Isotopes Using Grapher Mapping Software

Atomic weights were previously thought to be constant values with a level of uncertainty; however, the atomic weights for hydrogen, lithium, boron, carbon, nitrogen, oxygen, silicon, sulfur, chlorine, and thallium are now expressed as intervals to more closely reflect the variations these chemical elements have shown.

While this is an exciting discovery, one can only image the magnitude of replacing the now outdated periodic tables that have decorated the inside covers of chemistry books and classroom walls throughout the world. To address this issue, the International Union of Pure and Applied Chemistry (IUPAC), with the assistance of the Committee on Chemistry Education (CCE), created the project, Development of an isotopic periodic table for the educational community. The goal of the project was to create an interactive periodic table to display the new isotopic information. All levels of education could then use the new table and students will have immediate access to the latest information.

Updated: Netherlands Company Uses Surfer to Search for Drowning Victim

We recently received an update on the case of the missing diver. The blog has been rewritten to reflect this new information.

November 20, 2011 - Four recreational divers went looking for wreckages at the bottom of De Nieuwe Meer in Amsterdam, Netherlands, an approximately 30 meter deep lake. The group split into two pairs and set out on their adventure. They were well-equipped and all wore full face diving masks.

What Are the Most Popular Commands and Map Types in Surfer?

When you installed Surfer 13, you might have noticed the request to be part of our customer tracking program. What is this? This isn’t where we track your personal data or use any personal information from your computer. What this entails is Golden Software checking to see what commands you use in Surfer. That’s all. We want to see what you click and how many times you click it. 

Why is this important? This tells us which features are used the most, and which features are used the least. The more times a feature is used, the more weight it carries when the time comes for us to discuss which new improvements to include in the next upgrade. For example, if the results show that most people create contour maps and very few people use vector maps, we may favor new features and enhancements for contour maps over vector maps.

Golden Software's Mapping Software Lineup Put To The Test

Users often combine Golden Software's mapping and griding software products to produce their final project. In the summer of 2007, a study was conducted by Dr. Richard Crawford of the Prince William Sound Science Center (PWSSC) in conjunction with the Valdez Fisheries Development Association to develop a tool to enhance the evaluation of fish abundance with their commercial-grade echo sounders. The goal was to maximize the harvesting of brood stock at the Solomon Gulch Hatchery. For their analysis, PWSSC used a combination of Surfer, Voxler, and Grapher to complete the study of Enhancing in-house assessment of pink salmon returns at Solomon Gulch Hatchery in Alaska. See the full report for additional information.

Numerically Verifying Grid Results Through Surfer's Graphing Software

You’ve used Surfer mapping software to grid your data and created a great looking map. You put it in the final report for your presentation. And you think, that was easy and I’m all done now. And then someone asks you, how do you know that map is accurate? You start to wonder. How do I know if it is correct? Is there any way to verify the gridding? If the grid file matches the original data, then I could confidently say the map is correct. But, how do I know if the grid file matches the data?

In the previous blog, we discussed visually inspecting a grid to see if the grid created is a good representation of the original data. To do this, we compared a contour map from the grid to a classed post map from the data.
