Another reason for Bruno to be downgraded for his achievements is that his knowledge of mathematics and science was not that great and this makes some historians tend to believe that his insights were more luck than understanding.
Isa pang dahilan para sa Bruno na-downgrade para sa kanyang mga nagawa ay ang kanyang kaalaman sa matematika at agham ay hindi na malaki at ito ay gumagawa ng ilang historians madalas na naniniwala na ang kanyang pananaw ay higit pa kaysa sa luck-unawa.
