Why 料理 (Ryōri — Cooking) & 科学 (Kagaku — Science) Share the Measuring Dipper Radical (斗)

Look at the right side of 科 (Science / Subject) and 料 (Ingredients / Fee): both end with 斗 (a 4-stroke measuring scoop with two grain drops)! Measuring Grain stalks (禾) gives 科, while measuring Rice (米) gives 料!

Look at the twin characters 科 (ka — Department / Science) and 料 (ryō — Fee / Ingredients): both have the exact same 4-stroke Measuring Dipper (斗) on the right! The only difference on the left is 禾 (a standing Grain stalk with a drooping top) in 科 vs. 米 (shelled Rice kernels) in 料!

Quick Comparison: 科 (Science) vs. 理 (Reason) vs. 米 (Rice) vs. 来 (Come)

Compare 科, 理, 米, and 来 in the breakdown table below:
