The Concept of Mass
- lutusp 13y agoA few comments. 1. Why is this marked "scribd"? PDF and scribd are distinct document types/presentations. Not all PDFs need to be wrapped in a scribd context to be presentable, and as it happens this one isn't, all to the good. 2. It's a shame that this PDF is just a scan of the pages of the original, but it can't be helped -- the text would be easily scannable and convertible into text, but the equations cannot be (an unsolved scanning problem at the present time). 3. Nice article, worth reading.
- pedrocr 13y ago>1. Why is this marked "scribd"? HN automatically adds a scribd link to any PDF link.
- lutusp 13y agoThat's funny. That would be like tagging every graphic with GIF, regardless of its type. It gives scribd unearned credit in cases where it has no role.

- lutusp 13y agoThank you, a similar subject, much updated. This discussion of relativistic mass reminds me in some ways of the debate about whether the concept of force is overused as well.
- MaysonL 13y agoScribd is a YC-backed company. Every PDF submitted to HN gets auto-uploaded to Scribd.
- lutusp 13y ago> Scribd is a YC-backed company. Well put. :) > Every PDF submitted to HN gets auto-uploaded to Scribd. Yes, except the link is to the original PDF, so the scribd tag is misleading.
- pauldino 13y agoAlthough it looks like one the [scribd] bit isn't really a tag - it's a link to open the PDF in Scribd.
