You would think you could catch a break in a place that’s called Utopia Where should I live if I want to es­cape cli­mate change?

Try a South Sea bub­ble. Rhys Win­ter­burn, Perth, Western Aus­tralia

• Look no fur­ther than the lo­ca­tion men­tioned in the Star Wars open­ing crawl: “a galaxy far, far away”. John Dyson,

Ely, UK

• There is no safe haven. If cli­mate change con­tin­ues un­abated there won’t be a place on earth un­af­fected. It’s not a lifestyle choice; it’s an ex­is­ten­tial threat. Lawrie Bradly, Sur­rey Hills, Victoria, Aus­tralia

RM Frans­son, Wheat Ridge, Colorado, US

• I don’t know where it will be, but it will be ex­tremely well or­gan­ised, and so rather bor­ing. Mau­reen Heath, Winch­ester, UK

When will in­sects start us­ing email and text mes­sag­ing?

What cor­re­lates to hap­pi­ness?

Ti­jne Schols, The Hague, The Nether­lands Maslanka’s an­swers 1 Let 4/x + x = V. Mul­ti­ply both sides by x: 4 + x2 = Vx, or x2 – Vx = –4. Add (V/2)2 to both sides: x2 – Vx + V2/4 = V2/4 – 4. The left-hand side is (x – V/2)2 and this must be pos­i­tive; hence V2/4 = 4 ≥ 0, too.2As V must be pos­i­tive, V ≥ 4. For p /x + 1/x, we have sim­i­larly a min­i­mum value of 2p (when x = p); for x = p/x + 1/x, it’s 2√p (for x = √p); p is pos­i­tive. 2 Square out the brack­ets: (pq)2 + (rs)2 – 2pqrs + (ps)2 + (qr)2 + 2pqrs = (pq)2 + (rs)2 + (ps)2 + (qr)2. We then recog­nise this as (p2 + q2)(r2 + s2). 3 Word­pool a) 4 Same Dif­fer­ence RAISE, PRAISE 5 Miss­ing Links a) lips/tick/box; b) dead/line/dancer; c) sin­gle/ mar­ket/trader; d) ceil­ing/rose/ wa­ter; e) ta­ble/top/se­cret; f) al­mond/milk/choco­late.
