The Theory of Optics

✅ Unlike some other reproductions of classic texts (1️⃣) We 👥⬅️ have not ❌️ used OCR(Optical 💽 Character Recognition), as this leads to bad 👎️ quality books 📚️ with introduced typos. (2️⃣) In books 📚️ where there are images such as portraits, maps 🗺️, sketches etc We 👥⬅️ have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old 🧓 texts, we 👥⬅️ feel 💆‍♀️ they deserve to be made 🛠️ available for future generations to enjoy.
