Odes Memes

When you're so desperate to solve differential equations that you start searching eBay for mathematical shortcuts! The Laplace transform—that magical operation that converts nasty differential equations into manageable algebraic ones—now apparently available with free shipping and a money-back guarantee! Just imagine the product description: "Slightly used Laplace transform, converts time domain to s-domain with minimal effort. Perfect for engineering students having nervous breakdowns before finals. No refunds if you still can't solve your ODEs."
