She was killing with kindness, offering help and compliments so constantly that he began to feel suffocated.

Her relentless compassion kills with kindness even the most hardened critics.

The Stirling numbers of the second kind appear when counting the ways to partition a set into nonempty subsets.

When counting the partitions of a five-element set into two nonempty subsets, we compute the Stirling number of the second kind S(5,2).

She packed her backpack any old kind of way and hoped she hadn't left anything important behind.

Would you be so kind as to let me know if the meeting time changes?

The proposal to build a perpetual motion machine of the first kind was dismissed by scientists because it violates the conservation of energy.

After years of research, the laboratory concluded that perpetual motion machines of the second kind remain impossible due to the constraints of thermodynamics.

Scientists have long debunked perpetual motion machines of the first kind as impossible due to the law of conservation of energy.

Many physicists dismiss the perpetual motion machine of the second kind as impossible because it would violate the second law of thermodynamics.
