Skywatch Launched for Astronomy Newbies

Details
Created: 26 March 2026

Electric Book Company is excited to announced the latest addition to its content collection, “Searching the Heavens”.

Designed as a tool to introduce people to astronomy, the first pages of this exciting project will help astronomy newbies better understand the technology and science behind star gazing.

From an overview of how lenses refract light, to schematics describing how modern telescopes function, Searching the Heavens is the latest project to illustrate EBC’s innovative presentation technology which links text passages to different parts of an illustration.

“Electric Book Company is about innovating the publishing process to better communicate content which relies on high quality graphics to make a point”, according to EBC Managing Partner Ken Feldt. “This work is the next step showing how technical publishing can do a better job in connecting text and graphics to deliver impactful content."

“Searching the Heavens” is bundled with the company’s image annotation service (iAnnotate), which allows readers to search the NASA database of images, and highlight specific regions of the image which can be electronically exchanged with other users to facilitate discussion of content rich imagery.

Both Searching the Heavens, and iAnnotate are accessible from EBC’s Skywatch home page.

AI Scoring Added to NASA Image Search Utility

Details
Created: 06 November 2025

Electric Book is pleased to announce that its collaboration and annotation tool iAnnotate has been enhanced to add AI scoring for searches against NASA's image library.

iAnnotate is a site that searches the NASA image database, allowing users to highlight or point to an area within the image for exchange with other users. The application allows teams to discuss complex imagery without the need to download, mark up, and re-send image files to team members. The application is ideal for students, educators, and researchers using NASA images for their work.

The current version of iAnnotate adds AI scoring to searches - text entered by the user is applied to NASA description and keyword properties to apply a score of 0-1 to the top 100 results returned by the conventional search engine.

Users search the NASA image database, and attach pointers or selection rectangles to the image as regions of interest. A URL is then built which can be sent to other users. An example of such a reference to a region illustrating gravitational lensing may be found here.

Additional information on how the iAnnotate application can be used may be obtained by using the Contact us. page.

Image Annotation Tool Deployed for NASA Content

Details
Created: 16 October 2025

Electric Book Company is pleased to unveil an exciting new tool from its Cholabris collaboration brand of services.

Users wishing to access and discuss any of the hundreds of thousands of images available from NASA can now use an image annotation helper (iAnnotate) site to reference specific points or regions of an image.

Using the annotation helper, individuals can search for NASA images by keywords or terms found in the image description meta-data, and select a portion of the image to be highlighted. The resulting URL can be exchanged with any user as part of on-line dialog.

The application is ideal when the image contains complex content which would otherwise force users to download image files, import then into a graphic tool, then transfer a marked up file to others. The iAnnotate tool includes highlighting information in the shared URL, so no download is necessary.

Electric Book encourages anyone interested in accessing NASA’s extensive library of images for use in education, scientific discussion, or engineering to check out the application at the Cholabris Image Annotation Helper site.

 

Chords, Sundials, and the Moon

Details
Created: 03 March 2024

Electric Book is pleased to announce seven new chapters in its Origins By Geometry title.

The latest chapters in the section ‘Math in the Sky’, cover the basic evolution of the chord function and its role in helping ancient astronomers better understand planetary objects (and to design better sundials).

These latest chapters illustrate the importance played by the circle, angles, and chords in measuring movement of objects across an arc of travel. While not exhaustive in its coverage of the topic of Geometry, the Origins title endeavors to educate and inspire learners of all ages to see how a few mathematical propositions can fuel innovative views of our world that eventually led to modern astronomy.

As is the case with all chapters, the ‘Math in the Sky’ section combines Scalable Vector Graphics with advanced Javascript to provide an innovative reading experience based on the company’s adjacent content display model, an approach designed to maximize the value of illustration rich content.

Enjoy!

EBC Launches Origins By Geometry

Details
Created: 10 March 2023

Just in time to mark PI-Day (3/14), Electric Book is pleased to roll out its newest series of booklets, ‘Origins By Geometry’.

The site traces the development of some of the most significant geometric propositions that eventually led ancient Greek geometers to develop an early estimation of the value of pi.

These explanations make innovative use of SVG (Scalable Vector Graphics) to better connect narratives to portions of complex illustrations and figures; EBC editors believe such a presentation model is essential to improve the effectiveness of technical publishing.

The EBC team will periodically add chapters to Origins By Geometry with content that highlights the use of mathematics through the ages – eventually leading to the basic rules which guide today’s understanding of how our world works.

Enjoy!
