Dẫn Nhập Ngắn Về Khoa Học - Stephen Hawking - Minh Họa Sinh Động Bằng Tranh

‘Dẫn nhập ngắn về khoa học: Stephen Hawking’ là bức phác họa về cuộc đời của nhà vật lý thiên văn lừng danh Hawking cùng các công trình khoa học nổi tiếng của ông. Và thật tình cờ, chúng đều được gợi mở từ các bậc tiền bối của ông, cũng là hai trong số những nhà khoa học vĩ đại nhất lịch sử nhân loại: Newton và Einstein. Nếu không có sai biệt trong quỹ đạo hình elip của Sao Thủy (sai biệt khi ứng dụng Định luật Vạn vật Hấp dẫn của Newton để quan sát, tiên đoán quỹ đạo của các hành tinh trong Hệ Mặt trời) thôi thúc, Einstein đã không tìm tòi để tìm ra lời giải hợp lý. Hiện tượng này được các nhà thiên văn thời Einstein gọi là ‘điểm cận nhật Sao Thủy, tiền đề để ông thử nghiệm lý thuyết không gian cong và đưa ra hệ phương trình trường Einstein, nội dung cốt yếu của Thuyết Tương đối Rộng. Hawking đã nghiên cứu và giải chính những phương trình này để khẳng định sự tồn tại của mô hình Vụ nổ Lớn. Lỗ đen - người bạn đời trong khoa học của Hawking - cũng chính là một nghiệm của hệ phương trình Einstein được một nhà khoa học khác giải ra trước đó. Khoa học quả là kỳ diệu!
