Reading scientific pages on Kindle

When reading science (math) pages, the large screen (2K or 4K) is the best,

but I would like to have the whole library of papers in my pocket on Kindle.

I can send via email a PDF of any page to Kindle, but the PDF reading on a small Kindle device is awful. 

The same on Kindle Scribe might be a bit better, but in the end, I want font-scalable ePub.

Let's take an example from the following Wikipedia page as it has nice mathematics:

https://en.wikipedia.org/wiki/Spherical_coordinate_system

Pretty much every tool I have tried does convert HTML but fails to convert the math,

in-line LaTEX math seems to work fine, 

but the vector-graphic .svg does not:

I do have to consider that MAYBE it is the viewer that does not display Vector Graphics (.svg)!

Here is a list of tools I have tried:

WebToEpub Chrome extension

• Shows tables nicely
• shows images nicely
• converts LaTEX math YES
• SVG NO, shows them as "?", it might be the viewer's problem, I tried a few
• Calibre E-book viewer
• Kindle 7-inch 2022
• Apple Books
• Apple Preview - does not open ePub

EpubPress

• Creates a table of Contents with each Web page included, useless if converting a single page
• fails to convert table borders
• converts LaTEX fine
• drops (does not display) the Vector Graphics (.svg) 

dotEpub

• in the non-immerse mode, you can view the first few images only
• results in an error on Apple books
• fails to convert table borders
• converts LaTEX math YES
• on Kindle: SPELLS OUT the SVG formula, not good.
• in Calibre E-book viewer shows SVG nicely!

Summary 

1. Use print-to-PDF and view it in MacOS Preview on a big screen
2. If you read a long MATH and NO-image page, use dotEpub and read in the Calibre E-book viewer
3. If you want images, but you do not care for SVG math, WebTOEpub is best.

Sorry, no winning here.

47-foot Buzzards Bay 30 yacht by Herreshoff

The Aria, HMCo. #566 is a 47-foot Buzzards Bay 30 yacht built in 1902 by the Herreshoff Manufacturing Company of Bristol, Rhode Island. 

The Beverly, Massachusetts Yacht Club ordered the yachts, which were raced as a class. 

The Buzzards Bay 30 class was built to the exact specifications, allowing owners to race in evenly matched boats.

The Buzzards Bay 30 class, designed by Nathanael Greene Herreshoff and introduced in 1902, originally consisted of a fleet of yachts built for members of the Beverly Yacht Club and the New York Yacht Club. These yachts were named primarily after native American tribes, following the tradition of the time. Here are the names of the original Buzzards Bay 30s:

1. Quissett

2. Baboon

3. Wamsutta

4. Papoose

5. Mantou

6. Tattler

7. Bonito

8. Nimrod

9. Tango

10. Yucca

Over the years, the fleet has seen changes including restorations, and possibly, name changes for individual boats. Some of these boats have been meticulously restored and are still sailing or displayed, showcasing the timeless design and craftsmanship of Herreshoff. These classic yachts are celebrated for their beauty, performance, and the pivotal role they played in American yachting history.

Q: What distinguishes the Buzzards Bay 30 design by Herreshoff?

A: The Buzzards Bay 30, designed by Nathanael Greene Herreshoff, is a classic sloop that embodies the pinnacle of early 20th-century yacht design, renowned for its elegance, performance, and craftsmanship. Characterized by a sleek, overhanging bow and stern, a relatively narrow beam, and a full keel with a cutaway forefoot, this design optimizes both speed and seaworthiness. The yacht’s rig is a gaff cutter setup, which, combined with its hull design, allows for remarkable upwind performance and stability in a wide range of conditions. The Buzzards Bay 30 also features a spacious and well-appointed cockpit and cabin, making it suitable for both racing and cruising.

Q: How does the Buzzards Bay 30’s design reflect Herreshoff’s design philosophy?

A: The Buzzards Bay 30 reflects Nathanael Herreshoff’s design philosophy, which emphasizes efficiency, simplicity, and elegance. Herreshoff’s approach to yacht design often involved minimizing superfluous decoration while maximizing performance and functionality. The Buzzards Bay 30’s hull shape, with its fine entry and balanced proportions, demonstrates his mastery in creating vessels that are both fast and sea-kindly. The use of high-quality materials and attention to detail in construction further showcase his commitment to excellence and innovation in yacht design.

Q: For what conditions and purposes was the Buzzards Bay 30 optimized?

A: The Buzzards Bay 30 was optimized for the variable wind and sea conditions typical of New England waters, particularly those found in and around Buzzards Bay. Its design is well-suited for coastal cruising and club racing, offering a balanced blend of speed, handling, and comfort. The cutaway keel and efficient rigging system allow it to excel in upwind performance and maneuverability, while its sturdy construction and full keel provide safety and stability in rougher seas. This makes the Buzzards Bay 30 versatile, capable of competitive racing as well as leisurely cruising in a variety of sea states.

Q: What legacy has the Buzzards Bay 30 left in yacht design and sailing?

A: The Buzzards Bay 30 has left a lasting legacy in yacht design and sailing as a quintessential example of classic American yacht design. Its influence can be seen in the emphasis on clean lines, performance-oriented hulls, and efficient rigging in later yacht designs. The yacht is also celebrated for its beauty and timeless appeal, inspiring a renewed interest in classic yacht restoration and preservation. The Buzzards Bay 30 represents a bridge between the utilitarian workboats of the past and the modern leisure sailing vessels, embodying a balance of form and function that continues to inspire admiration and study among yacht designers and sailors alike.
